[en] Possible mechanisms of light nuclei fragment production are studied. Correlation < n_b>=f(n_g) for light nuclei-projectiles of ²²Ne with kinetic energy 3.7 GeV/nucleon is considered. The received results showed that behavior of mean number of fragments and their mean charges in dependence of interacted protons (n_g^') indicate realisation of both fragmentation mechanisms - the vapor one under small n_g^' and multi-fragmentation - under large one. A-dependence of characteristics relating to these both mechanisms is revealed as well
