Systematics of coalescence radii for light-fragment emission from energetic heavy-ion collisions

The refined coalescence model has been applied to the analysis of triton and helion (3He) spectra from various heavy-ion colliding systems atEinc/A∼(15÷25) MeV/nucleon. The results show that the obtained coalescence radii increase with increasing asymmetry of the colliding system. A similar trend was observed previously for alpha and deuteron spectra.
