Total reaction and neutron-removal cross sections of(30–60)A MeVBe isotopes on Si and Pb

Nuclear-matter distribution in the proton-rich nuclei 7Be and 8B from intermediate energy proton elastic scattering in inverse kinematics

“…The value of R m = 2.42(4) fm for 7 Be derived in this work coincides within the errors with the result of Warner et al [34], but exceeds essentially the value of R m = 2.31(2) fm obtained by Tanihata et al [17]. A comparison of the rms radii R m and R p calculated using different theoretical models together with the experimental values is presented in Table 3.…”

“…For both investigated nuclei, a good description of the cross sections was obtained with all the used density parameterizations. The value of R m = 2.42(4) fm deduced for 7 Be is larger than the matter radii obtained in previous experiments based on measurements of the total interaction [17] and reaction [34] cross sections. On the other hand, the present R m value is in perfect agreement with most of the theoretical predictions (Table 3).…”

“…Information on the structure of 7 Be, the presumable core of 8 B, is rather scarce. The matter radii R m = 2.31(2) fm [17] and R m = 2.36(6) fm [34] were obtained through measurements of the interaction and reaction cross sections. The proton radius R p = 2.507(17) fm [35] was derived from the charge radius R ch measurement in a laser spectroscopy study [36].…”

Applicability of 9Be global optical potential to reactions of 7,10,11,12Be *

“…The calculations are in agreement with the data. Moreover, there is some experimental data [17] above 100 MeV, and a good agreement is likewise obtained in this region. For , some experimental data [18,19] originate from the natural silicon target, and the theoretical results are in reasonable agreement.…”

“…To improve the results, the coupled-channel calculations will be considered in the future work. For the total reaction cross-sections of on light targets, only the experimental data [17] for at incident energies of 224.0 and 350.7 MeV is available. The data at 18.8 MeV is obtained by analyzing the experimental data of elastic angular distributions [25,26] using the coupled-channel method.…”
