2-DIMENSIONAL NUCLEAR INERTIA - ANALYTICAL RELATIONSHIPS

The components of the nuclear inertia tensor, functions of the separat ion distance R and of the radius of the light fragment R(2) B-RR(R,R(2 )), B-RR2(R,R(2)), and BR(2)R(2)(R,R(2)) are calculated within the Wer ner-Wheeler approximation, by using the parametrization of two interse cted symmetric or asymmetric spheres. Analytical relationships are der ived. When projected to a path R(2)=R(2)(R), the reduced mass is obtai ned at the touching point. The two one-dimensional parametrizations wi th R(2) = const, and the volume V-2 = const previously studied, are fo und to be particular cases of the present more general approach, Illus trations for the cold fission, cluster radioactivity, and ct decay of Cf-252 are given.
