Study of the shell effect on nuclear dissipation via neutron multiplicity measurement
Abstract
Experimental neutron multiplicity data has been fitted using the Kramers’ fission width, in statistical model calculations with and without inclusion of shell corrections in nuclear level density, nuclear masses and fission barrier. It has been found that the magnitude of dissipation strength changes to a large extent with inclusion of shell corrections in different ingredients of the statistical model. These observations clearly demonstrate the importance of shell corrections in statistical model calculations.
