Abstract
The
1/2+ ground state and a
11/2- isomer of very neutron-deficient isotope
were produced by irradiation of an enriched target of
with
and studied by
using a helium-jet fast tape-transport system in combination
with proton-
, X-
and
-
coincidence measurements.
A simple (
) decay scheme of
with a half-life of 3.0(3) s and a tentative (
)
decay scheme of
with a
half-life of 5.6(10) s are proposed. As a by-product, the 347- and 545-keV
transitions in
following the
-delayed proton emission of
decay and the 323-keV
transition
in
following the
-delayed
proton emission of
decay could be observed
for the first time.
