**deformation**is invariant under some rotations , it is no longer possible to specify the orientation of the system uniquely , and the rotational degrees of freedom are correspondingly reduced . The rotations that leave the ...Page 5

**deformations**that are invariant with respect to any subgroup of the full rotation group . ... For example , an axially symmetric**deformation**with an octupole component ( pear shape ) is invariant with respect to ...Page 198

This behavior of the

**deformation**can be understood as a simple shell effect . For a given nucleon number the shell structure causes an oscillation in the total binding energy as the**deformation**is increased , giving rise to shell ...### What people are saying - Write a review
