In deep-inelastic collisions of 8 MeV/nucleon 70Zn projectiles with 198Pt, we have found an 8+ isomer with T1/2=23(1)ns at 4208 keV in 68Ni; the νg9/2 E2 effective charge was determined to be 1.5(1)e. In 69Cu, a 19/2− isomer with T1/2=22(1)ns at 3691 keV was identified and its decay data were calculated quite accurately by a parameter-free shell model calculation using empirical input parameters. Proton 2p- 1h excitation, fed by another T1/2=39(6)ns isomer at 3827 keV, induces large collectivity in 69Cu.

Ichikawa Advanced Science Research Center Japan Atomic Energy Research Institute Tokai Ibaraki 319-1195 Japan Department of Liberal Arts and Sciences National Defense Medical College Tokorozawa Saitama 359-8513 Japan Research Laboratory for Nuclear Reactors Tokyo Institute of Technology Meguro Tokyo 152-8550 Japan

Gamma-ray cascades from nanosecond isomers in neutron-rich nuclei 67Cu and 64Co have been observed through heavy-ion deep-inelastic collisions of 198Pt+76Ge (8 MeV/nucleon) using an isomer-scope. In 67Cu, an isomeric state at 3464 keV and its decay scheme have been established. The isomeric transition is a hindered M1 transition between the 15/2+ and the 13/2+ states with main components of (πp3/2νg9/2νf5/2−1)15/2+ and (πp3/2νg9/2νp1/2)13/2+, respectively. A fast E3 transition between the πg9/2 and the πp3/2 single-particle states indicates strong particle-octupole vibration coupling in 67Cu. An isomeric state at 834 keV with T1/2=6.4(3)ns has been identified in 64Co. Proton-neutron configurations of the levels established in 64Co are discussed.

(νg9/2−2)8+ isomers in82Se48 and 80Ge48 populated by deep-inelastic collisions

Physical Review C 1999年第5期59卷 R2331(R)-R2331(R)页

作者： A. Makishima M. Asai T. Ishii I. Hossain M. Ogawa S. Ichikawa M.

New 8+ isomers in 82Se and 80Ge and their decays were studied by observing γ rays from the projectilelike fragments produced by the deep-inelastic collision 198Pt+743 MeV82Se. The lifetimes of the 8+ isomers have been measured to be T1/2=6.6(4) ns and T1/2>0.4 ns for82Se and 80Ge, respectively. The N=48 isotones from 3280Ge to 4694Pd turned out to show quite different energy spectra of the yrast states up to Iπ=8+, depending on the orbital occupied by valence protons.

The (νg9/22νp1/2−2)8+ isomer with T1/2=23(1) ns at 4208 keV in 68Ni was found by deep-inelastic collisions of 70Zn(8 MeV/nucleon)+198Pt and the νg9/2 E2 effective charge was determined to be 1.5(1)e.

Lifetime measurement of the πg9/2 isomer in 79As

引用

Physical Review C 1998年第2期58卷 1318-1318页

作者： I. Hossain T. Ishii A. Makishima M. Asai S. Ichikawa M. Itoh M. Ishii P. Kleinheinz M. Ogawa Research Laboratory for Nuclear Reactors Tokyo Institute of Technology Meguro Tokyo 152-8550 Japan Advanced Science Research Center Japan Atomic Energy Research Institute Tokai Ibaraki 319-1195 Japan Department of Liberal Arts and Sciences National Defense Medical College Tokorozawa Saitama 359-8513 Japan

The lifetime of the 773 keV πg9/2 isomer in 79As has been measured to be T1/2=0.87(6) μs by taking coincidences between γ rays and projectilelike fragments produced in deep-inelastic collisions of 198Pt+76Ge (635 MeV). The B(M2,9/2+→5/2−) value for the 542 keV transition in 79As is found to be 0.042(3) Weisskopf units (W.u.). An identification method of nuclei produced in deep-inelastic collisions is also described.

The (νg9/22πp3/2)19/2− Isomer in C71u and the Prediction of its E2 Decay from the Shell Model

Physical Review Letters 1998年第19期81卷 4100-4100页

作者： T. Ishii M. Asai I. Hossain P. Kleinheinz M. Ogawa A. Makishima S. Ichikawa M. Itoh M. Ishii J. Blomqvist Advanced Science Research Center Japan Atomic Energy Research Institute Tokai Ibaraki 319-1195 Japan Research Laboratory for Nuclear Reactors Tokyo Institute of Technology Meguro Tokyo 152-8550 Japan Department of Liberal Arts and Sciences National Defense Medical College Tokorozawa Saitama 359-8513 Japan Physics Department Royal Institute of Technology S-10405 Stockholm Sweden

In deep-inelastic collisions of 8 MeV/nucleon 76Ge projectiles with 198Pt, we have found a T1/2=0.25(3)μs isomer in 71Cu which decays through a γ-ray cascade of 133-495-939-1189 keV to the πp3/2 ground state. The detector setup records the γ rays of the isomeric decay as well as data on the fragment which provide its isotopic assignment. The new 71Cu levels are firmly assigned as the five yrast states of the νg9/22πp3/2 configuration; a parameter-free shell model calculation using the two-body residual interactions as observed in 70Cu and 70Ni predicts the 71Cu data with excellent accuracy.

OX14 2EG UK AbstractCited by AbstractNuclear incineration a process in which the radioactive waste products from the operation of nuclear reactors are transmuted to stable or short lived products offers a method of reducing the long term hazards of nuclear waste. The topic was studied in some detail in the 1970s when it was concluded that the benefits were marginal because the hazards from geological disposal were considered to be small. However there has been a recent resurgence of interest. A historical review of the process is given though no attempt is made to consider all the work that has been performed. The basis on which the initial conclusions were drawn is explained the present status of the technique is described and conclusions are drawn.

Nuclear incineration, a process in which the radioactive waste products from the operation of nuclear reactors are transmuted to stable or short lived products, offers a method of reducing the long term hazards of nuclear waste. The topic was studied in some detail in the 1970s, when it was concluded that the benefits were marginal because the hazards from geological disposal were considered to be small. However, there has been a recent resurgence of interest. A historical review of the process is given, though no attempt is made to consider all the work that has been performed. The basis on which the initial conclusions were drawn is explained, the present status of the technique is described, and conclusions are drawn. Background information needed to understand the process is also presented.
