Description
Preliminary results of an experiment to detect γ transitions between the high energy particle unstable structures known in the 12C+12C system are reported. The specific process investigated is (12C+12C) 25.8 MeV(c.m.)→γ+(12C+12C) 19.3 MeV(c.m.)→γ+12C+12C (g.s. or 2+). The initial energy is near the center of the gross structure thought to have J/sup π/ = 14+, and 19.3 MeV is the energy of the 12+ intermediate width resonance. An upper limit (one standard deviation) is found (GAMMA/sub γ//GAMMA)/sub 25.8tsMeV/< or approx. =(1 to 4) x 10-6 depending on the analysis procedure. This result shows there is no collective γ decay between the intermediate width resonances at the energies studied here, and is comparable in size and consistent with resonance-fragmentation models but does not exclude nonresonant ones
