The Liquid Drop Model for Nuclear Fission

Nuclear Shape Fluctuations in Fermi-liquid Drop Model

Within the nuclear Fermi-liquid drop model, quantum and thermal fluctuations are considered by use of the Landau-Vlasov-Langevin equation. The spectral correlation function of the nuclear surface fluctuations is evaluated in a simple model of an incompressible and irrotational Fermi liquid. The dependence of the spectral correlation function on the dynamical Fermi-surface distortion is establis...

Jellium Correction on the Critical Condition of Cluster Fission within a Liquid Drop Model

Jellium correction on the fissionability parameter is estimated within a Liquid Drop Model of the charged metallic cluster. This correction modifies the critical condition of fission and, it becomes relevant for small multicharged clusters. PACS numbers: 36.40.Qv, 36.40.-c Adapting the Liquid Drop Model (LDM) from nuclear physics to the description of finite systems (metallic clusters) [1, 2] o...

Nuclear Liquid Drop Model with the Surface-Curvature Terms: New Perspectives for the Hyperdeformation Studies

Nuclear liquid drop model is revisited and an explicit introduction of the surface-curvature terms is presented. The corresponding parameters of the extended classical energy formula are adjusted to the contemporarily known nuclear binding energies and fission barrier heights. Using 2766 binding energies of nuclei with Z ≥ 8 and N ≥ 8 it is shown that the performance of the new approach is impr...

Generalized Liquid Drop Model and Fission, Fusion, Alpha and Cluster Radioactivity and Superheavy Nuclei

A particular version of the liquid drop model taking into account both the mass and charge asymmetries, the proximity energy, the rotational energy, the shell and pairing energies and the temperature has been developed to describe smoothly the transition between one and two-body shapes in entrance and exit channels of nuclear reactions. In the quasi-molecular shape valley where the proximity en...
