Nucleon Distributions in Loosely Bound Nuclei

Abstract

The radioactive ion beam (RIB) facility allows to study highly unstable loosely bound nuclei which may lie even close to drip line. One of the aims of such studies (e.g. see [1, 2]) is to extract the information about neutron density distributions in such exotic nuclei. For this purpose, one uses the Glauber model. The Glauber model requires the proton and neutron density distributions of both the target and the projectile. If the target density distribution is reasonably known then the neutron density distribution of the projectile can be extracted knowing its proton distribution. In fact it has been possible to reproduce the observed cross sections in the Glauber model by fitting parameter(s) appearing in a reasonably assumed form for the neutron density distribution of the projectile (exotic loosely bound nucleus) [1, 3, 4]. Such an analysis may give reliable information about the size of the nucleus, but may not determine correctly the shape of the density distribution.
