Cluster pre-existence probability
- 1. Bharathiar University, Department of Physics, Coimbatore (India)
Description
Pre-existence probability of the fragments for the complete binary spectrum of different systems such as 56Ni, 116Ba, 226Ra and 256Fm are calculated, from the overlapping part of the interaction potential using the WKB approximation. The role of reduced mass as well as the classical hydrodynamical mass in the WKB method is analysed. Within WKB, even for negative Q -value systems, the pre-existence probability is calculated. The calculations reveal rich structural information. The calculated results are compared with the values of preformed cluster model of Gupta and collaborators. The mass asymmetry motion is shown here for the first time as a part of relative separation motion. (orig.)
