A new formula for the nuclear level density is derived without the use of the saddle-point approximation. The dependence of the level density on the finite dimension of the vector space is explicitly seen. The effect of the neglect of higher moments of the level-density distribution in the ...
The nuclear one-body dissipation formula, which describes the time rate of exchange of energy from a moving nuclear surface into internal excitation under the assumption of a long mean free path is derived here from the Fermi-gas solution of the Boltzmann equation instead of from classical mechani...
Define key words such as matter, mass, volume, density, and buoyancy. Use the density formula to solve density example problems for density,...
A new formula for the nuclear charge radius is proposed, dependent on the mass number A and neutron excess N-Z in the nucleus. It is simple and it reproduces all the experimentally available mean square radii and their isotopic shifts of even-even nuclei much better than other frequently use...
