| Abstract: | The kinetic part of the classical Hamiltonian, which describes both symmetric and asymmetric nuclear fission, has been computed as a quadratic form in the time derivatives of parameters determining the (sharp) nuclear surface. We treat the nucleus as an irrotational, non-viscous and incompressible fluid and solve the problem without using the “Wheeler assumption”.An appropriate three-parameter description of the nuclear surface is chosen, and effective masses with respect to these parameters are computed numerically. Some of our results can be compared with those obtained by other authors. |
