The fragmentation of quasi-projectiles from the nuclear reaction
40Ca+12C at 25 MeV/nucleon was used to produce excited states
candidates to α-particle condensation. The methodology relies on high
granularity 4Ď€ detection coupled to correlation function techniques. Under
the assumption that the equality among the kinetic energies of the emitted
α-particles and the emission simultaneity constitutes a reliable
fingerprint of α condensation, we identify several tens of events
corresponding to the deexcitation of the Hoyle state of 12C which fulfill
the condition.Comment: 5 pages, 3 figure
