Abstract
A survey of neutron-deficient nuclides which can be produced via proton- and 3He -induced fusion-evaporation reactions in the A = 100 region was made using a Penning trap as a high-resolution mass filter. A comparison of the measured isotopic rates with a statistical model calculation for the proton-induced reactions shows the importance of using the precise binding energy values for the final reaction products. In particular, proton separation energies were found to play an important role in the evaporation process. In addition, accurate masses of 12 nuclides, 97-99, 101Pd , 100Ag , 101-105Cd and 102, 104In , were determined with uncertainties of less than 10keV.
