Abstract
The radioactive decay of
was investigated by means of
-
-spectroscopy.
Fine structure in the ground-state
-decay was established.
Ambiguities in the
fine structure of the
-decay of the previously known isomeric state
could be clarified by
-
-coincidence measurements.
A previously unknown
-transition of
= (8306
5) keV
was detected and identified by means of delayed
-
-
and
-
-
-coincidence measurements.
A second isomeric state decaying by
-emission was not observed.
The quality of the previously reported data
of the
-decay fine structure of
was improved.
