Study of the 22Ne(d, d)22Ne, 22Ne(d, p)23Ne, 22Ne(d, t)21Ne and 22Ne(p, d)21Ne reactions

Abstract The nuclear reactions 22 Ne(d, d) 22 Ne, 22 Ne(d, p) 23 Ne and 22 Ne(d, t) 22 Ne induced with 12.1 MeV deuterons and 22 Ne(p, d) 21 Ne induced with 18.2 MeV protons have been studied by employing a gas target of enriched 22 Ne and beams accelerated in the Livermore variable energy cyclotron. The results have been analysed with the nuclear optical model and DWBA calculations. The neutron-transfer reactions have been compared with the predictions of the Nilsson model. The results for the pick-up reactions going to the first three levels of 21 Ne are in good agreement with the predictions of the Nilsson model. The RPC model (rotational and particle motion with Coriolis band mixing) modified for pairing effects was employed in an effort to obtain at least a qualitative explanation of the transitions leading to 23 Ne. There are certain large discrepancies consisting of strong transitions that are predicted theoretically under a wide range of assumptions but not seen experimentally. These results indicate that further detailed calculations are necessary to understand the structure of this nucleus.
