BOSE-EINSTEIN CORRELATIONS AND MULTIFRAGMENTATION IN RELATIVISTIC HEAVY-ION COLLISIONS

It has been shown that the scale measured through Bose-Einstein correl ations (BEG) reflects an intrinsic scale of the order of the meson Com pton wavelength. In heavy-ion collisions however, the radii of the pio n emission region obtained are close to the effective nuclear radius o f the lighter nucleus. We show that BEC in a multifragmentation pictur e of heavy-ion collisions is compatible with the two facts and that it is therefore possible to use Bose-Einstein interference to obtain a g eometrical description in this kind of reactions. We outline the possi bility to use Bose-Einstein correlations to learn something about mult ifragmentation.
