Mass Measurement of100Sn

Abstract
Secondary ions of 100Ag, 100Cd, 100In, and 100Sn were produced via the fusion-evaporation reaction 50Cr+58Ni at an energy of 51 MeV/nucleon, and were accelerated simultaneously in the second cyclotron of GANIL. About 10 counts were observed from the production and acceleration of 100Sn22+. The masses of 100Cd, 100In, and 100Sn were measured with respect to 100Ag using the GANIL cyclotron, with precisions of 2×106, 3×106, and 105, respectively.
