Abstract

The 6^6Li(n,γ\gamma)7^7Li cross sections in the neutron energy range of 0.6 to 4 MeV have been measured by the experimental implementation of the direct capture formalism. This was done by measuring the γ\gamma transition probability experimentally and accounting for the spin factor by theoretical calculation. The electromagnetic transition probabilities from 7^7Li^* analogous to the initial neutron capture states of 6^6Li+n+n were measured by populating the Ji_i states of 7^7Li through 7^7Li(p,pp,p')7^7Li^* reaction. The impact of coupling of resonant states, above neutron separation threshold of 7^7Li, in the neutron capture, is observed from the capture γ\gamma spectrum. The measured cross sections were reproduced through {\sc fresco} and Talys-1.95 Direct Capture Calculations.
