Abstract
has been produced via the reaction using 23-40-MeV ions. Identification is made from the observed rays of 1431.3 ± 0.5, 1847.69 ± 0.25, and 2538 ± 2 keV which agree with the first three excited states of . By means of the reaction , rays from the first two excited states of have been measured as 1431.4 ± 0.3 and 1847.60 ± 0.15 keV. The three rays decay together and a value of sec is obtained from the 1848-keV line. Relative intensities correspond to branches to the 1431-, 1848-, and 2539-keV states of in the ratios 0.06 ± 0.06: 1: 0.10 ± 0.02. No information was obtained on a possible ground-state branch. The results are consistent with the expected mass and spin-parity () of the ground state.
