The Masses of A ≈ 60-70 Nuclei Close To The N = Z Line

摘要

The masses of very neutron-deficient ~(66)As, ~(68,70,71)Se and ~(71)Br were measured for the first time and those of ~(64,65)Ge and ~(67)As remeasured, with total uncertainties ranging from 200 to 1000 keV, including systematic, extrapolation and statistical errors, using the SPEG direct time-of-flight method at GANIL. These new results are discussed and compared to other recent experimental data and mass predictions.
