Abstract
In recent experiments at GANIL, we studied nuclei at the one- and
two-proton drip line.
The production rates allowed to search for direct 2p emission
in the drip line nuclei
42Cr,
45Fe, and
49Ni. No evidence
for this decay mode was found in
42Cr and
49Ni, whereas the situation
stays unclear for
45Fe due to the limited statistics.
In the medium-mass region
(
), the half-life was
measured for all proton-rich nuclei in the range
Tz=0 to
Tz=-1 between
Z=27 and
Z=36. First half-lives were determined for
60Ga,
62Ge,
64As and
66Se.
Finally,
-decay studies of the
decay of
62Ga have been performed at IGISOL in Jyväskylä.
Non-analog transitions have been observed and are compared to
theoretical predictions.
