Abstract
The energy spectrum of 2.5× particles from the sequential decay has been analyzed. Superimposed on the broad energy distribution which originated from the decay of the 9.60 MeV state of into , a group of 9538 ± 1810 particles with an energy of 1282 keV has been identified with a maximum error of ± 5 keV. This group is attributed to the parity non-conserving decay from the 8.87 MeV state of into ; the -particle emission width for this decay has been determined to be = (1.03 ± 0.28) × eV. In a separate measurement the relative decay branching ratio to the 9.60 and 8.87 MeV states in , which was necessary for the calculation of , has been determined to be (9.98 ± 0.70) × .
