The excitation energy spectrum has been obtained from coincidence measurements of the reaction at E0=52 . The decay of the states at excitations between 10 and 16 into has been observed for the first time. Observed -decay indicates possible cluster structure of the excited states. The influence of these states on the cross-section of the astrophysically important ( ) and reactions is discussed and the results are compared with existing results.
