15N elastic and inelastic scattering by 11B at 84 MeV

Elastic and inelastic scattering of 14N ions by 11B at 88 MeV versus that of 15N + 11B at 84 MeV

“…The deformation parameters of 11 B and 14 N found in previous scattering analyses involving these nuclei [2,4,5] were found to describe the inelastic scattering in the present work. The 11 B + 14 N scattering potential was found to be quite similar at the three highest 14 N energies studied here and should be considered to be well determined for this system.…”

“…3, the measured distribution of the 11 B + 14 N elastic scattering at the energy E lab ( 14 N) = 88 MeV (filled symbols) is compared with that of 11 B + 15 N distributions at E lab ( 15 N) = 84 MeV [2] (open symbols) as a function of transferred momentum qt. One can see that these data are very similar.…”

“…8(b) show that they differ only slightly in their imaginary parts so that the scattering for these pair of nuclei is independent of the nitrogen isotope involved in the reaction. 14 N. In the CRC-calculations, the form-factor V λ (r) (2) and deformation parameters δ λ of 11 B and 14 N listed in Table 1 were used. In Figs.…”

“…In the case of 11 B + 14 C scattering the large angle cross section is more than a factor of two less, and is produced by a combination of potential scattering and reorientation of 11 B [1]. A recent work reporting the results of 11 B + 15 N scattering carried out to explore the possibility of alpha particle exchange between these two nuclei demonstrated that again the large angle scattering was generated by a combination of contributions from potential scattering and reorientation of 11 B with very little contribution from alpha particle exchange [2]. The present work reports the results of the scattering of 11 B + 14 N to explore further the systematics of the scattering between members of an isotopic chain.…”

Scattering of $^{15}$N Ions by $^{10, 11}$B Nuclei at the Energy of 43 MeV

“…In calculations, this behavior can be reproduced by taking into account the contribution of nucleon or cluster of nucleons transfer between the projectile and the target nucleus. Recently, elastic scattering and α-cluster transfer between 15 N and 11 B at 84 MeV has been studied by Rudchik et al [4] and a significant increase in the differential cross sections at backward angles was observed. It is known that the contribution of transfer reactions strongly depends on the structure of the two interacting nuclei, as well as on the beam energy.…”
