Abstract

Recent experimental efforts were made to explore the Bose-Einstein condensation in multi- $α$ system using the heavy-ion collisions. This Letter provides a explanation why no signatures were observed and a guidance for future experiments. More precisely, a harmonic oscillator model is developed to study the multi- $α$ source at or near zero temperature. The temperature and particle population of the multi- $α$ sources observed in the current experiments are extracted. It is found that almost no $α$ particles occupy the ground state in those multi- $α$ sources. The critical temperature for the multi- $α$ -condensed states are predicted, which provides a guidance for the future experiments to probe the Bose-Einstein condensation of $α$ clusters in the heavy-ion collisions.
