The “superallowed” 108Xe -> 104Te -> 100Sn double alpha-decay chain has been recently observed at Argonne National Laboratory. This is the first observation of N = Z alpha emitters, in which the enhanced proton-neutron interaction should lead to large alpha-particle preformation factor, and thus, exceptionally fast alpha decay. However, only an upper limit was obtained for the 104Te half-life, and the alpha-particle energies were measured with modest accuracy. A novel plastic scintillator-based detector setup will be developed for the focal plane of the new MARA separator in order to improve these observations. The results to be obtained in this study will provide insight on the role of the proton-neutron interaction in the alpha particle preformation.
