The average binding energy, radii, effective inverse level density parameter, and heat capacity are calculated within both methods for Sn110-130 even-even isotopes. The results are compared with other calculations. We have shown that all of the studied quantities behave smoother as a function of temperature when the gap parameter of the modified Ginzburg-Landau model is used. The heat capacities show S-shaped behavior. (C) 2021 Elsevier B.V. All rights reserved.

The energies and wave functions of the eigenvalue problem are obtained in compact form by using the asymptotic iteration method. The numerical results of the energy spectrum and the electric quadrupole transition ratios are calculated and compared with the experimental data for Xe-128,Xe-130,Xe-132 and Pt-192,Pt-194,Pt-196 nuclei as well as other theoretical models. In this way, it is highlighted the importance had by the effect of the shape flatness of the Kratzer potential and the deformation dependent mass term on the numerical predictions in relation to the experimental data.

The physics goal of the BES program is the search for a conjectured QCD critical point as well as for manifestations of the chiral magnetic effect. We describe progress that has been made over the previous five years. This includes studies of the equation of state and equilibrium susceptibilities, the development of suitable initial state models, progress in constructing a hydrodynamic framework that includes fluctuations and anomalous transport effects, as well as the development of freezeout prescriptions and hadronic transport models. Finally, we address the challenge of integrating these components into a complete analysis framework. This document describes the collective effort of the BEST Collaboration and its collaborators around the world. (c) 2021 Elsevier B.V. All rights reserved.
