Abstract
Mass measurements of the N = Z nuclei 80Zr, 76Sr, 68Se were performed for the first time and a new measurement was obtained for 80Y, using the second cyclotron CSS2 of GANIL as a high-resolution spectrometer. Ions around N = Z were produced by fusion-evaporation in the inverse 58Ni (4.32 MeV A) + 24Mg and 12C reactions. New masses were measured by a time-of-flight method, with a precision of 2 · 10-6, by using well-known masses as references. Study of the double binding energy difference δV np is then performed leading to a strong N = Z Wigner effect around N = Z = 40. Knowledge of new masses in this region also plays a crucial role in the modelling of the astrophysical rp process.
