摘要
Inertia mass parameter B in a fissioning nucleus is calculated. The method of calculation is based on the assumption of adiabatic collective motion in the fission degree of freedom. Resulting values for B are 4 to 11 times larger than those obtained from the liquid-drop model estimates. It turns out that the inertial parameter increases almost linearly with nuclear deformation. It also appears to be a sensitive function of the pairing force strength. Rough estimates of the coupling between quadrupole and hexadecapole modes seem to indicate that it may modify considerably the obtained results. The calculations are extended to the predicted superheavy region connected with Z ≈ 114. © 1969.
