| 英文摘要 | The beta-delayed two-proton emission from Al-22 was investigated experimentally through the implantation-decay method. A beta-delayed two-proton decay branch from Al-22 were identified based on the coincidence of the charged particles and.-ray signals. The relative momentum (q(pp)) and the opening angle (theta(pp)) distributions of the two beta-delayed protons are measured and a strong peak at q(pp) similar to 20 MeV/c, as well as a peak at theta(pp) similar to 30 degrees are observed clearly. The beta-delayed He-2 emission from Al-22 with a probability of 29 (13)% by fitting the experimental data with the results of Monte Carlo simulations. (c) 2018 The Author(s).
