Elastic, inelastic, and 1n transfer cross sections for the B10+Sn120

Abstract

The 10 B + 120 Sn reaction has been investigated at E Lab = 37.5 MeV. The cross sections for different channels, such as the elastic scattering, the excitation of the 2 + and 3 − 120 Sn states, the excitation of the 1 + state of 10 B, and the 1n pick-up transfer, have been measured. One-step distorted-wave Born approximation and coupled-reactionchannels calculations have been performed in the context of the double-folding São Paulo potential. The effect of coupling the inelastic and transfer states on the angular distributions is discussed in the paper. In general, the theoretical calculations within the coupled-reaction-channels formalism yield a satisfactory agreement with the corresponding experimental angular distributions.

“…In such scenario, it could be important to include couplings to continuum states in order to describe simultaneously the elastic scattering and the different reaction channels. As part of the E-125 experimental campaign, the 10 B + 120 Sn reaction has already been measured at 37.5 MeV and analysed within the CRC formalism [25]. In the present work, we report on new experimental results obtained for the same reaction measured at E LAB = 31.5, 33.5 and 35.0 MeV.…”

“…SATURN is being developed as a portable nuclear reaction spectrometer, based on silicon detectors telescopes, desktop-type electronic modules, and multi-channel acquisition systems. SATURN is installed in the 30B experimental beam line of the laboratory, which contains a scattering chamber connected to the 8MV pelletron tandem accelerator [24,25].…”

“…The aim of the project is to study the scattering involving the light weakly-bound stable nuclei 6 Li, 7 Li, 9 Be, 10 B and 11 B, on the same heavy target ( 120 Sn), at energies around the Coulomb barriers, and compare the respective results among them as well as with others reactions involving exotic nuclei 6,8 He, 8,9,11 Li, 10,11 Be. These reactions with the 120 Sn target have produced many channels of inelastic excitation and transfer, which can be conveniently separated in the experimental energy spectra [24,25]. The analyses of the different nuclear reactions processes, at several energies and within the same theoretical approach, represent a powerful breakthrough.…”

“…In the next section, the experimental setup presented in [24,25] is revisited. Then, we present the experimental data and respective theoretical analyses.…”

Investigation of the one-neutron transfer in C13+Si28 at Elab<

“…For the 13 C + 28 Si system, the Coulomb barrier height is V B = 18.9 MeV (in the laboratory reference). [14], mounted in the scattering chamber for the measurements. A set of 9 surface barrier Si detectors was mounted at 30 cm away from the targets and with 5 • of angular step size, covering the angles from 25 • to 65 • (laboratory framework).…”
