Unbound Li nuclei as ejectiles in α-induced pickup

Breakup phenomena in nuclear collision processes with He projectiles

“…Comparison of the shape of the normalization constant N(e), which is corrected for the 8 dependence of the DWBA cross section, with the double differential cross section as function of the relative energy for the J V =Y > E x = 3.62 MeV state in 29 Si (after van Driel, Kamermans, de Meijer, and Dieperink, 1980). 12 C, 24 Mg(a, 5 Li) n B, 23 Na reactions at 65-MeV incident energy (Saha et aL, 1978).…”

“…Three typical fitted spectra are shown in Figs. 2 -o, elastic differential cross sections were deduced from the yields of elastically scattered n particles. These were smaller than those previously reported [7] and were therefore renormalized.…”

“…In-our experiment we lose any knowledge of the a-n correlations. This loss of knowledge overcomes difhculties of similar experiments [2], which have employed coincident a ndetection, withresulting directional bias in selection of 5He decays and unknown efficiency [2,5].…”

“…Measurements [2] pared with the binding energy of the transferred nucleon [3]; thus our energy may be high enough to suitably test the theory even though the transferred neutron is bound by 20 MeV in He. Next, by detecting the final He we achieve 100'%% detection efficiency, thereby observing final states including all directions of the a-n relative momentum vector in the He system.…”
