Abstract: | A new improved nuclear partition function is employed to calculate
the nuclear statistical equilibrium (NSE) in core-collapse supernova
environment. The results show that the change of nucleus abundance
is slight even though the temperature is higher than 10$^{11}$\,K
when shock propagates, which indicates that the effect of the
nuclear partition function is not so important as shown in the
previous calculations, but it can also be considered in detailed
simulation if it is sensitive to weak interaction rates in
core-collapse supernova. |
