Analytical approach to electromagnetic processes in loosely bound nuclei: application to 8B
In this paper we develop an analytical model in order to study
electromagnetic processes involving loosely bound neutron--rich and
proton--rich nuclei. We construct a model wave function, to describe loosely
bound few--body systems, having the correct behaviour both at large and small
distances. The continuum states are approximated by regular Coulomb functions.
As a test case we consider the two--body Coulomb dissociation of 8B and, the
inverse, radiative capture reaction. The difference between using a pure
two--body model and the results obtained when incorporating many--body effects,
is investigated. We conclude that the interpretation of experimental data is
highly model dependent and stress the importance of measuring few--body
channels.Comment: Accepted for publication in Physics Letters B. Added a comparison
