DIRECT AND SEQUENTIAL CONTRIBUTIONS TO THE MG-26(LI-6(LI)OVER-RIGHT-ARROW, HE-6)AL-26 REACTION AT 60 MEV

Angular distributions of differential cross-section and vector analyzi ng power have been measured for the Mg-26(Li-6 over arrow pointing rig ht, He-6)Al-26 reaction, populating four states in Al-26, at an incide nt energy of 60 MeV. Distorted-wave Born approximation (DWBA) calculat ions were performed for the (Li-6 over arrow pointing right, He-6) pro cess using shell-model spectroscopic amplitudes and microscopic form f actors derived from the M3Y interaction. Sequential contributions to t he charge-exchange reaction mechanism via the (Li-6 over arrow pointin g right,Li-7)(Li-7, He-6) and (Li-6 over arrow pointing right, Li-7)( Li-7, He-6) processes were calculated using the coupled-channels Born approximation (CCBA). The effects of inelastic couplings in Li-6 were also examined.
