Abstract

Angular distributions for the elastic scattering of 52 MeV deuterons were measured from 27 nuclei ranging from hydrogen to uranium. The experimental data have been analysed in terms of the optical model. The inclusion of a vector spin-orbit term in the potential is necessary for nuclei with A > 100. For light nuclei with 12 ≦ A ≦ 50, good fits to the experimental angular distributions could also be obtained without a spin-orbit potential. The optical-model parameters for nuclei with $A ≧ 12$ are discussed with respect to the dependence on the energy E, the charge Z and the mass A. The A-dependence of the real potential depth V can be understood as a consequence of the spatial polarization of the deuteron during the scattering process. Discrepancies between optical-model calculations and experimental angular distributions observed in the elastic scattering processes from ¹H, ³He, and ⁴He indicate contributions from transfer reactions.

Effect of compound nuclear reaction mechanism in 12C(Li6,d) reaction at sub-Coulomb energy
2017, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The angular distribution of the ¹²C( ${}^{6}{Li}$ ,d) reaction populating the 6.92 and 7.12 MeV states of ¹⁶O at sub-Coulomb energy (E ${}_{c m}=$ 3 MeV) are analysed in the framework of the Distorted Wave Born Approximation (DWBA). Recent results on excitation function measurements and backward angle angular distributions derive ANC for both the states on the basis of an alpha transfer mechanism. In the present work, we show that considering both forward and backward angle data in the analysis, the 7.12 MeV state at sub-Coulomb energy is populated from Compound nuclear process rather than transfer process. The 6.92 MeV state is however produced from direct reaction mechanism.
Pairing resonances and the continuum spectroscopy of 10Li

In fact, compared to a pure BCS calculation the fluctuations are reduced because they are determined by the overlap of the bound hole and the unbound particle wave function. The Nogami–Lipkin method [39] seems to be an approach feasible also for the more involved case of a continuous spectrum. Work in this direction is in progress.
Pairing across the particle emission threshold and the properties of corresponding quasiparticle strength functions are discussed in an extended mean-field approach. This particular type of dynamical correlations gives rise to a unique class of sharp low-lying resonances close to the particle emission threshold. Spectral functions for particle and hole states are discussed. They are explored theoretically by single-nucleon transfer reactions, populating the low energy continuum with respect to a core nucleus. The cross sections of the reaction d(⁹Li, ¹⁰Li)p at $T_{lab} = 2.36 A MeV$ , recently measured at REX-ISOLDE, are well reproduced by our calculations including a pairing resonance in the $3 / 2^{-}$ partial wave of purely coupled channels nature.
