Abstract

The fragmentation of quasi-projectiles from the nuclear reaction ⁴⁰Ca+¹²C 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 α-particle clustering in excited ¹⁶O, ²⁰Ne and ²⁴Mg are reported.
