Gamma ray transitions de-exciting states in the N = Z nucleus Br-70 have be
en identified for the first time using the GASP and EUROBALL arrays coupled
with ancillary detectors. The level scheme of Br-70 has been established b
y means of particle-gated gamma-gamma and gamma-gamma-gamma coincidences. T
he Coulomb energy differences between isobaric analogue states in Br-70 and
Se-70 show a deviation from the expected behaviour which could be related
to dripline effects.
