Abstract

Probing nucleon-nucleon correlations via heavy ion transfer reactions

Highlights

  • Transfer reactions have an important impact in the understanding of correlations in the nuclear medium, and play a very important role for the study of the evolution from the quasi-elastic to the deep-inelastic and fusion regime [1]

  • Making use of the semi-classical approximation it has been possible to extend the concept of elementary modes of excitation in the reaction model that allowed to quantitatively study reactions that involve the transfer of many nucleons, and to predict how the total reaction cross section is shared between different channels

  • Heavy-ion transfer reactions are an ideal tool for the study of the residual interaction in nuclei, in particular the components responsible for the couplings between the single particle and phonon degrees of freedom, as well as particle correlations

Introduction

Transfer reactions have an important impact in the understanding of correlations in the nuclear medium, and play a very important role for the study of the evolution from the quasi-elastic to the deep-inelastic and fusion regime [1]. The recent revival of transfer reaction studies greatly benefited from the construction of the new generation large solid angle spectrometers based on trajectory reconstruction that reached an unprecedented efficiency and selectivity. The coupling of these spectrometers with large γ arrays allowed the identification of individual excited states and their population pattern. In particular how single particle and more complex degrees of freedom act in the transfer process
