Examination of Single Particle Excitation of 15C using the Continuum Discretized Coupled Channels Method

ORAL

Abstract

Previous analysis of 7.1 MeV/u 15C(d,d')15C* experimental data obtained with the HELIOS detector used a rigid rotor model to represent quadrupole deformation [1]. However, due to the low neutron separation threshold of 15C, 1.218 MeV [2], it is expected that 15C breakup plays a role in the 15C+d reaction.

In this work, we study the 15C+d reaction using a three-body model of 14C+n+d and the Continuum Discretized Coupled Channels (CDCC) method. Results will be presented for the elastic, inelastic, and breakup channels of this reaction. A comparison to the rigid rotor model will be discussed. We find the need to include breakup in the reaction mechanism.
