Description

The new proton-rich nucleus 104Sn was produced in a 50Cr(58Ni, 2p2n)104Sn reaction. Its half-life was measured to be 21+-1 s. From a newly established partial decay scheme, a Qsub(EC) value of 4,000 (+650-300) keV was estimated. The resulting mass excess value for 104Sn, combined with decay energies for α and proton emission, leads to mass excess values for the nuclei 108Ti, 109I, 112Xe, and 113Cs. These mass values are compared to predictions of mass formulae. (orig.)
