Influence of the emitter Coulomb field on two-proton correlation function

摘要

The experimental two-proton correlation functions measured in (sup 36)Ar+(sup 45)Sc at 80 MeV/nucleon have been compared with predictions of a new three-body quantum model which includes the Coulomb interaction of the particles with their emitter. For a realistic charge of the source, its Coulomb field strongly influences the shape of the correlation function leading to a significant reduction of the source radius deduced in the two-body approximation. The differences in the shape of the correlation function observed between the data and theoretical results highlight the limits of a static picture of the source and the importance of dynamical correlations.
