Abstract

Gamma rays emitted isotropically may be strongly polarized under special circumstances. A measure of the linear polarization of such a gamma ray or lack of it can help to eliminate several of the spin solutions which are consistent with the observed isotropy. By combining the results of linear polarization measurements with other published information, it was possible to show that the 2.00 MeV level in 11C had spin Jπ = 12 and the 4.90 MeV level in 14N has Jπ = 0(1). The parity of the 5.10 MeV level is negative. It thus has = 2.
