Circular polarization of neutron capture γ-rays from Mn,Ni, Ga and W

Capture γ-ray circular polarization measurements on the Mn(n, γ), Ni(n, γ), Ga(n, γ) and W(n, γ) reactions with polarized neutrons resulted in unambiguous spin assignments for 20 levels, 10 of which confirmed previous assignments. For another 20 levels the number of possible spin values has been reduced.
