For nuclear level densities, a modification of an enhanced generalized\nsuperfluid model with different collective state enhancement factors is\nstudied. An effect of collective states on forming the temperature is taken\ninto account. The ready-to-use tables for the asymptotic value of a-parameter\nof level density as well as for addition shift to excitation energy are\nprepared using the chi-square fit of the theoretical values of neutron\nresonance spacing and cumulative number of low-energy levels to experimental\nvalues. The systematics of these parameters as a function of mass number and\nneutron excess are obtained. The collective state effect on gamma-ray spectra\nand excitation functions of neutron-induced nuclear reactions is investigated\nby the use of EMPIRE 3.1 code with modified enhanced generalized superfluid\nmodel for nuclear level density.\n
