Abstract
Preliminary results of an experiment to detect transitions between the high energy particle unstable structures known in the + system are reported. The specific process investigated is ( + ) 25.8 MeV (c.m.) → + ( + ) 19.3 MeV (c.m.) → + + (g.s. or ). The initial energy is near the center of the gross structure thought to have MeV is the energy of the intermediate width resonance. An upper limit (one standard deviation) is found depending on the analysis procedure. This result shows there is no collective 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.
NUCLEAR REACTIONS Compared + → + ( + ) and () + () 's; MeV; deduced upper limit.
