Validity of the adiabatic molecular orbital concept in the interaction of heavy ions

Abstract

Molecular orbital formation of nucleons in the interaction of heavy ions is of interest because it defines the intrinsic states constructed from the system of colliding particles and also it furnishes us with new aspects on heavy ion reaction mechanism I) . Up to now, however, there is little evidence for the formation of molecular orbitals. Here, we consider, in connection with CRC theory, in what situation the molecular orbitals are formed and how the concept of molecular orbital is useful in understanding the scattering, 13C(12C,12C) 13C~(gr.,i/2-; 3.086MeV, I/2+; 3.854MeV; 5/2 + ) (ref. 2,3) We assume that rotating molecular orbitals (RMO) are formed with the basis functions defined in refs. I-3. In the RMO representation transitions between the states of ~p and ~q are induced by the coupling interaction containing the radial kinetic energy operator T(r) (radial coupling) (A-l[T,A])pq = ~(~ (r)d/dr + A~(2)pq (r)~
