Octupole Type Deformation of Nuclear Surface
Department of Physics, Osaka City University, Osaka
(Received September 6, 1958)
The shell structure dependence of the surface rigidity to nuclear octupole type deformation is examined. In order to calculate the energy change due to octupole type deformation, a coordinate transformation which transforms a deformed surface into a spherical one is introduced. The results of our calculations are in good agreement with the trend of experimental data suggested by low lying odd parity states of even-even nuclei and display a characteristic shell structure dependence as well as quadrupole type deformation. According to the deformed potential model, it is shown that octupole type deformations are closely connected with quadrupole type deformations. This fact may play an important role in determining the spin values of low lying odd parity states of even-even nuclei and in understanding a mechanism of asymmetric fission.
