The parity of the 3134 keV,J=1 State in18F

The¹⁶O(³He,?γ)¹⁸F reaction atE(³He)=2.95 MeV was used to study the low-lying states in¹⁸F belowE _x =3.2 MeV. A combination of γ-ray angular distribution and linear polarization measurements using a single planar Ge(Li) polarimeter resulted in aJ ^π =1^? assignment to the 3134 keV state. In addition, the positive parity assignments to the 937(3⁺) and 1702(1⁺) keV states have been verified. Information on branching and mixing ratios as well as on lifetimes are reported. The results are discussed in terms of the weak-coupling and strong-coupling models.
