The first 2^(+)excited states of the nucleus directly reflect the interaction between the shell structure and the nucleus,providing insights into the validity of the shell model andnuclear structure *** the features of the first 2^(+)excited states can be measured for stable nuclei and calculated using nuclear models,significant uncertainty *** study employs a machine learning model based on a light gradient boosting machine(LightGBM)to investigate the first 2^(+)excited ***,the training of the LightGBM algorithm and the prediction of the first 2^(+)properties of 642 nuclei are ***,detailed comparisons of the LightGBM predictions were performed with available experimental data,shell model calculations,and Bayesian neural network *** results revealed that the average difference between the LightGBM predictions and the experimental data was 18 times smaller than that obtained by the shell model and only 70%of the BNN prediction *** Mg,Ca,Kr,Sm,and Pb isotopes as examples,it was also observed that LightGBM can effectively reproduce the magic number mutation caused by shell effects,with the energy being as low as 0.04 MeV due to shape ***,we believe that leveraging LightGBM-based machine learning can profoundly enhance our insights into nuclear structures and provide new avenues fornuclearphysicsresearch.

The multifaceted impact of shape coexistence on the first-forbidden β− decay of the 0− ground state of Y98 and the structure anddynamics of the populated low-spin states in Zr98 have been investigated within the complex excited Vampir variational model using an effective interaction derived from a G matrix based on the charge-dependent Bonn Cd potential and a large model space. The effects of shape coexistence and mixing revealed by the properties of the investigated β decay of Y98 and the coexistence phenomena at low angular momentum in Zr98 are discussed and comparison to the available data is presented.

The effects of shape coexistence on first-forbidden β− decay of the 0− ground state of rb92 to the 0+ ground state and 2+ states in Sr92 were studied within the beyond-mean-field complex excited Vampir variational model. The structure of the parent anddaughter states and the β-decay properties were investigated using an effective interaction derived from a G matrix based on the charge-dependent Bonn Cd potential and a large model space. The effects of shape coexistence and mixing revealed by the structure of the involved states on the properties of the investigated ground state to ground state and first-forbidden unique transitions are discussed and comparison to the available data is presented.

With ultrafast laser systems reaching presently 10 PW peak power or operating at high repetition rates,research towards ensuring the long-term,trouble-free performance of all laser-exposed optical components is *** work is focused on providing insight into the optical material behavior at fluences below the standardized laser-induceddamage threshold(LIdT)value by implementing a simultaneous dual analysis of surface emitted particles using a Langmuir probe(LP)and the target current(TC).HfO_(2) and ZrO_(2) thin films deposited on fused silica substrates by pulsed laserdeposition at various O_(2) pressures fordefect and stoichiometry control were irradiated by Gaussian,ultrashort laser pulses(800 nm,10 Hz,70 fs)in a wide range of *** TC and LP collected signals were in good agreement with the existing theoretical description of laser–matter interaction at an ultrashort time *** approach for an in situ LIdT monitoring system provides measurable signals for below-threshold irradiation conditions that indicate the endurance limit of the optical surfaces in the single-shot energy scanning *** LIdT value extracted from the LP-TC system is in line with the multipulse statistical analysis done with ISO 21254-2:2011(E).The implementation of the LP and TC as on-shot diagnostic tools for optical components will have a significant impact on the reliability of next-generation ultrafast and high-power laser systems.
