Abstract
was produced by the reaction by bombarding with a beam of 19-MeV helium ions from the Purdue cyclotron. The was observed to decay by alpha emission with a half-life of 0.20±0.04 sec. The kinetic energy of the alpha particles emitted in the decay was measured using Au-Si surface-barrier charged particle spectrometers. The alpha-decay energy was found to be 7.87±0.07 MeV. The relative excitation function of the reaction was also obtained in the center-of-mass energy range from 17.87 to 18.86 MeV. The hindrance factor for the decay is calculated using the experimentally measured alpha-decay energy.
