INVESTIGATION OF QUASI-STATIONARY ALPHA-CLUSTER STATES IN O-16 BY ANALYSIS OF ANGULAR T-ALPHA CORRELATIONS

A theoretical analysis of the differential and double differential cro ss sections (t-alpha angular correlation function) has been performed for the O-16 excited states produced in the C-12(Li-7,t)O-16(alpha)C- 12 reaction at E(Li) = 34 and 45 MeV. The mechanism of semiheavy ion i nteraction has been studied and leads to the formation of high-lying q uasistationary a-cluster states in O-16. Calculations of the reaction characteristics are performed using the original computer codes in the EFR-DWBA and the Hauser-Feshbach model. The analysis of the angular c orrelation function has made it possible to establish new features of nuclear interactions in highly excited states.
