Structure in the 180° scattering ofC12byAl

Global optical model potential describing 12C-nucleus elastic scattering *

“…The results fit the experimental data well below and produce the average at the backward-angle, where the data present a strong oscillatory pattern. We also predict the angular distribution of 12 C + 27 Al and compare it with the existing experimental data [40][41][42][43]. Similarly, agreement is found for the forward-angles, where there is no oscillatory pattern, while the results produce an average description for backwardangles.…”

“…Figure 5 presents the fit of the calculations to the experimental data [25,26] for 40 Ca at incident energies of 50.96 and 180.0 MeV and compares the predictions and experimental data [26] at 300.0 and 420.0 MeV. Finally, it provides comparisons for isotopes, Ca, at incident energies of approximately 50 MeV.…”

Elastic scattering of10C +27Al

“…Figure 4 presents the obtained angular distribution for 10 C on 27 Al (circles). For comparison, data previously reported [3] for the neighboring (normal) system 12 C + 27 Al (squares) are also shown, which correspond to a similar energy in the center of mass reference frame (E c.m. ∼ 21 MeV).…”

“…Both statistical uncertainties and estimated angle uncertainties have been included. For comparison, earlier data [3] reported for the stable 12 C on 27 Al system at nearly the same energy in the center of mass reference frame are also shown.…”

Study of transfer reaction channel in $^{12}$C + $^{27}$Al system

“…In the present work, the elastic scattering angular distributions for the 12 C + 27 Al reaction have been measured at energies 73, 81 and 85 MeV. Previously, this system was studied at various energies [21,23,24] and 55 MeV was the highest incident energy found in the literature. At this energy the potential parameters were V (r)(32.31, 1.23, 0.57) and W F (r)(27.71, 1.12, 0.67) and r C = 1.31 fm [21].…”
