Alpha-particle clustering in excited expanding self-conjugate nuclei

摘要

The fragmentation of quasi-projectiles from the nuclear reaction ~(40)Ca+~(12)C at 25 MeV/nucleon was used to produce α-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 a-particle clustering in excited ~(16)O, ~(20)Ne and ~(24)Mg are reported.
