Alpha-particle clustering in excited expanding self-conjugate nuclei

Abstract

The fragmentation of quasi-projectiles from the nuclear reaction 40Ca + 12C at 25 MeV/nucleon was used to produce alpha-emission sources. From a careful selection of these sources provided by a complete detection and from comparisons with models of sequential and simultaneous decays, strong indications in favour of $\hat{I}\pm$-particle clustering in excited 16O, 20Ne and 24}Mg are reported.
