Findings

Inertial functions decrease with deformation development.

Comparison shows differences between ASCC and cranking formulae.

Pair rotation properties vary in gauge and real spaces.

Abstract

The adiabatic self-consistent collective coordinate (ASCC) method is used to determine the optimum reaction path and to calculate the potential and the inertial functions of the reaction model. The properties of the inertial functions are investigated with the ASCC method, in comparison with those of the cranking formulae. In addition, the properties of the pair rotation are investigated in the BCS pair model. The moments of inertia for rotation in both the real and the gauge spaces may decrease as the deformation develops.
