Description
The experimental evidence points to the existence, at short distances, of strongly correlated neutron-proton pairs much like they are in the deuteron or in free scattering processes.
As it moves through the nuclear medium, a “bare” nucleon in the presence of the nucleon-nucleon interaction becomes “dressed” in a quasi-deuteron cloud, about 20% of the time. Our phenomenological analysis of the independent-particle model content in a dressed nucleon [1] has an isospin dependence which is also reflected on the dressed amplitude. Thus, the qualitative arguments above, suggest that quasi-free scattering (QFS) of deuterons could offer a sensitive probe to examine these concepts.
In this contribution, we will discuss these ideas and present an experiment that aims at measuring the (p,pd) QFS cross-section for knocking out a deuteron in $^{10,14,16}$C relative to $^{12}$C as a tool to probe short-range correlations and their isospin dependency.
