Abstract
The linear polarizations of rays, produced in the reaction with MeV, have been measured with a Ge(Li) two-crystal Compton polarimeter. These polarization values were used with previously obtained -ray angular distribution measurements to make unique parity assignments for several states. The 641- and 1619-keV rays have been found to be predominantly transitions, and odd parity has been assigned to the levels at 2999 keV (), 3925 keV (), 4635 keV (), 4981 keV (), and 5681 keV (). Even parity assignments have been confirmed for levels at 991 keV (2+), 2736 keV (4+), 3994 keV (6+), and 4237 keV (6+). Also, the spin assignments for levels at 2307 keV (4+) and 4635 keV () have been confirmed.
