  Davidson et al. has extended Seeger's mass formula to non-zero excitation
energies by introducing temperature-dependent coefficients in the liquid drop
energy part of the semi-empirical mass formula, without considering the shell
effects. The semi-empirical mass formula of Davidson et al. is applicable for
the compound nucleus temperatures less than or equal to 4 MeV. The mass excess
calculated using this mass formula including shell effects/corrections does not
reproduce the ground state mass excesses of the new atomic mass evaluation data
AME2020 and/or FRDM(2012) with its coefficients at zero temperature. So, the
coefficients of the semi-empirical mass formula are needed to be tuned to
reproduce the ground state mass excess of the nuclei in the recent atomic mass
evaluation data AME2020 and/or FRDM(2012). The bulk and neutron-proton
asymmetry coefficients of the semi-empirical mass formula of Davidson et al.
with shell effects have been tuned to reproduce the mass excess data for all
the nuclei of AME2020 (Z=1-118 and A=1-295) and the nuclei of FRDM(2012)
(Z=8-136 and A=16-339, except 3456 nuclei which are also available in the
AME2020 data) at zero temperature, i.e., the coefficients are tuned for 9420
nuclei known at present. The tuned bulk and neutron-proton asymmetry
coefficients reproduce the mass excess of the new atomic mass evaluation data
AME2020 and/or FRDM(2012) within a difference of less than 1 MeV and can be
used for the applications/investigations in the areas of physics where high
energies are experienced or nuclei involved are in excited states, e.g.,
fusion-evaporation and fusion-fission processes in heavy-ion reactions.
