The adsorption behavior of Am(III) on granite (sampled from drilling well BS01 at Beishan (BS) area-a potential candidate site for China's high-level radioactive waste repository, the granite sample's depth about 300 m) was studied in BS03 well groundwater by a batch technique at (251)°C. The influences of pH, sulphate ion, total carbonate ion, humic acid, and concentration of the Am(III) on the adsorption behavior were also studied, and the possible adsorption mechanism was discussed. Experimental results show that the adsorption distribution rate of Am(III) on granite increases with increasing pH of aqueous phase. The chemical composition of the groundwater is the main factor which influences the species of Am(III) and adsorption behavior. The adsorption mechanism of Am(III) on granite is surface complexation. The adsorption isotherm of Am(III) on granite can be described by Freundlich's equation.

Differential measurements of the elliptic (v2) and hexadecapole (v4) Fourier flow coefficients are reported for charged hadrons as a function of transverse momentum (pT) and collision centrality or number of participant nucleons (Npart) for Au+Au collisions at sNN=200 GeV. The v2,4 measurements at pseudorapidity |η|≤0.35, obtained with four separate reaction-plane detectors positioned in the range 1.0<|η|<3.9, show good agreement, indicating the absence of significant Δη-dependent nonflow correlations. Sizable values for v4(pT) are observed with a ratio v4(pT,Npart)/v22(pT,Npart)≈0.8 for 50≲Npart≲200, which is compatible with the combined effects of a finite viscosity and initial eccentricity fluctuations. For Npart≳200 this ratio increases up to 1.7 in the most central collisions.

Hard-scattered parton probes produced in collisions of large nuclei indicate large partonic energy loss, possibly with collective produced-medium response to the lost energy. We present measurements of π0 trigger particles at transverse momenta pTt=4–12 GeV/c and associated charged hadrons (pTa=0.5–7 GeV/c) vs relative azimuthal angle Δϕ in Au+Au and p+p collisions at sNN=200 GeV. The Au+Au distribution at low pTa, whose shape has been interpreted as a medium effect, is modified for pTt<7 GeV/c. At higher pTt, the data are consistent with unmodified or very weakly modified shapes, even for the lowest measured pTa, which quantitatively challenges some medium response models. The associated yield of hadrons opposing the trigger particle in Au+Au relative to p+p (IAA) is suppressed at high pT (IAA≈0.35–0.5), but less than for inclusive suppression (RAA≈0.2).

By virtually re-creating and visualizing an intelligent space (iSpace) geographically far from the original version, one opens up the possibility of remote control and interaction between the real iSpace and the virtual copy. Here we present the required components for such a mixed environment: the actual iSpace in a form of a laboratory built for such experiments, the stereoscopic (real 3D) visualization tool at the far end to reproduce the original iSpace, and the middleware embodied by the computer network that connects the two. To remotely operate in the iSpace one has to overcome the important problem of synchronization that is made difficult by the time delay in the computer network. Here we present our first approach to solve this problem by demonstrating a successful remote control of a mobile robot in this mixed environment.

We report the measurement of the transverse momentum dependence of inclusive J/ψ polarization in p+p collisions at s=200 GeV performed by the PHENIX Experiment at the Relativistic Heavy Ion Collider. The J/ψ polarization is studied in the helicity, Gottfried-Jackson, and Collins-Soper frames for pT<5 GeV/c and |y|<0.35. The polarization in the helicity and Gottfried-Jackson frames is consistent with zero for all transverse momenta, with a slight (1.8 sigma) trend towards longitudinal polarization for transverse momenta above 2 GeV/c. No conclusion is allowed due to the limited acceptance in the Collins-Soper frame and the uncertainties of the current data. The results are compared to observations for other collision systems and center of mass energies and to different quarkonia production models.

It has been postulated that partonic orbital angular momentum can lead to a significant double-helicity dependence in the net transverse momentum of Drell-Yan dileptons produced in longitudinally polarized p+p collisions. Analogous effects are also expected for dijet production. If confirmed by experiment, this hypothesis, which is based on semiclassical arguments, could lead to a new approach for studying the contributions of orbital angular momentum to the proton spin. We report the first measurement of the double-helicity dependence of the dijet transverse momentum in longitudinally polarized p+p collisions at s=200 GeV from data taken by the PHENIX experiment in 2005 and 2006. The analysis deduces the transverse momentum of the dijet from the widths of the near- and far-side peaks in the azimuthal correlation of the dihadrons. When averaged over the transverse momentum of the triggered particle, the difference of the root mean square of the dijet transverse momentum between like- and unlike-helicity collisions is found to be −37±88stat±14syst MeV/c.

We report the first measurement of transverse single-spin asymmetries in J/ψ production from transversely polarized p+p collisions at s=200 GeV with data taken by the PHENIX experiment in 2006 and 2008. The measurement was performed over the rapidity ranges 1.2<|y|<2.2 and |y|<0.35 for transverse momenta up to 6 GeV/c. J/ψ production at the Relativistic Heavy Ion Collider is dominated by processes involving initial-state gluons, and transverse single-spin asymmetries of the J/ψ can provide access to gluon dynamics within the nucleon. Such asymmetries may also shed light on the long-standing question in QCD of the J/ψ production mechanism. Asymmetries were obtained as a function of J/ψ transverse momentum and Feynman-x, with a value of −0.086±0.026stat±0.003syst in the forward region. This result suggests possible nonzero trigluon correlation functions in transversely polarized protons and, if well defined in this reaction, a nonzero gluon Sivers distribution function.

New measurements by the PHENIX experiment at the Relativistic Heavy Ion Collider for η production at midrapidity as a function of transverse momentum (pT) and collision centrality in sNN=200 GeV Au+Au and p+p collisions are presented. They indicate nuclear modification factors (RAA) which are similar in both magnitude and trend to those found in earlier π0 measurements. Linear fits to RAA as a function of pT in 5–20 GeV/c show that the slope is consistent with zero within two standard deviations at all centralities, although a slow rise cannot be excluded. Having different statistical and systematic uncertainties, the π0 and η measurements are complementary at high pT; thus, along with the extended pT range of these data they can provide additional constraints for theoretical modeling and the extraction of transport properties.
