Abstract
The very neutron-deficient isotope 
was produced in the reaction 
at 195 MeV and was identified using the Daresbury recoil separator. A pure 
-ray spectrum belonging to the de-excitation of the excited states of was obtained in-beam. Twenty -ray lines were identified, ten of them for the first time. The intensity balance concerning some of these -rays together with the results obtained from the coincident measurements show the existence of a new set of levels which may be interpreted as being a side band confirming the coupling of 
and 
configurations.
