Neutron spectra from (p,n) reaction on the 165Ho, 204Pb, 206Pb, 207Pb, 208Pb, 209Bi nuclei and nuclear level density

Neutron spectra from the (p, n) reaction on the 165Ho, 207Pb, 208Pb, 209Bi nuclei have been measured at the proton energy of 6.95±0.15 MeV. The experimental data together with the data obtained earlier at Ep=11 MeV on the 165Ho, 204Pb, 206Pb, 207Pb, 208Pb, 209Bi nuclei have been analyzed within the framework of a statistical nuclear reaction theory using the generalized model of a superfluid nucleus for the nuclear level density. The absolute nuclear level density has been determined in a wide range of excitation energies. 16 refs.; 7 figs.; 1 tab
