摘要
The damping of the nuclear shell effect with excitation energy has been measured through an analysis of the neutron spectra following the triton transfer in the Li-7 induced reaction on Tl-205. The measured neutron spectra demonstrate the expected large shell correction energy for the nuclei in the vicinity of doubly magic Pb-208 and a small value around W-184. A quantitative extraction of the allowed values of the damping parameter gamma, along with those for the asymptotic nuclear level density parameter (a) over tilde, has been made for the first time.
