Abstract
The directional angular correlation between the 1.16- and 2.10-Mev gamma rays which follow the decay of 32.4-minute has been measured. Samples of were produced in the cyclotron of the University of California, Los Angeles by the () reaction and were produced in both solid and liquid form. Sodium iodide scintillation counters with subsequent pulse-height discrimination and standard coincidence techniques were used and the method was tested on the cascade of giving satisfactory agreement with previous results. The results on , although not unambiguous, are consistent with the assignment of spin 2 and even parity to both the first and second excited states of with the 1.16-Mev gamma ray being 1.7% electric quadrupole and 98.3% magnetic dipole radiation.
