Contour integral method for thermal and quantal fluctuations
K. Kaneko, M. Hasegawa
The partition function by means of the static path approximation (SPA) plus the random-phase approximation (RPA) treatment can be written as a contour integral form without solving…
Unique features of structure in an odd-proton nucleus As
M. Hasegawa, K. Kaneko, T. Mizusaki
We apply a large-scale shell model to the study of proton-rich odd-mass nuclei with . Calculations predict unexpected structure in the As nucleus for which a de…
Proton-neutron pairing energies in N=Z nuclei at finite temperature
K. Kaneko, M. Hasegawa
Thermal behavior of isoscalar and isovector proton-neutron (pn) pairing energies at finite temperature are investigated by the shell model calculations. These pn pairing energies c…
Quenching of pairing gap at finite temperature in 184W
K. Kaneko, M. Hasegawa
We extract pairing gap in W at finite temperature for the first time from the experimental level densities of W, W, and W using "thermal" odd-even m…
Structure of isomeric states in 66As and 67As
M. Hasegawa, Y. Sun, K. Kaneko +1
Strong residual correlations between neutrons and protons in N ~ Z systems can lead to unusual structure. Using the spherical shell model, we show that a low-excitation shape isome…
An alternative understanding of mass formulas in terms of nuclear structure
M. Hasegawa, K. Kaneko
A typical form of mass formula is re-explained in terms of nuclear structure. For nuclei, we propose to start with the shell model picture and to consider the T=0 $…
