How strong is the absorption in the 12C + 20Ne system

“…The results are shown in figure 2 together with the results of Doubre et al [3]. It is seen that the observed cross-sections at 90~ and beyond are of the order of the two estimates of the compound nuclear crosssections.…”

“…In a recent communication [3] of another study of 12C + 2°Ne elastic scattering were reported. In this work the excitation functions at more backward angles, 90° and 1300, were measured as well as at 700 c.m.…”

“…It is seen that the observed cross-sections at 90~ and beyond are of the order of the two estimates of the compound nuclear crosssections. In figure 3 we compare the angular distribution of reference [3] with the Hauser-Feshbach predictions. The calculations reproduce the absolute magnitude of the cross-sections but underestimate L-163 HOW STRONG IS THE ABSORPTION IN THE 12C + 2°Ne SYSTEM ?…”
