Abstract
We show that coalescence of nucleons emitted prior to thermalization in hig hly excited nuclei can explain the anomaly of kinetic energies of helium cl usters. A new coalescence algorithm has been included in the statistical ap proach to nuclear reactions formerly used to describe intermediate mass fra gment production.
