What is the physics behind the 3He-4He anomaly?

Neubert, W.; Botvina, A. S.

Abstract

We show that coalescence of nucleons emitted prior to thermalization in highly excited nuclei can explain the anomaly of kinetic energies of helium fragments. This mechanism accomplishes the statistical approach to nuclear rections formerly used to describe intermediate mass fragment production.

Keywords: Intermediate energy hadron -nucleus and nucleus-nucleus interactions; helium isotopes
