[en] The γ-ray decay of the 1612 keV level (tau=6.38+-0.15 ns) in ³⁷Ar has been analyzed in terms of a mixture of three multipoles. The data was obtained from the simultaneous measurement of the linear polarization and angular distribution of the decay γ rays, in coincidence with the neutrons emitted along the beam axis, the level being populated via the ³⁴S(α,n)³⁷Ar reaction at Esub(α)=10.5 MeV. The results definitively eliminate the possibility of the γ rays consisting of a mixture of three multipoles, thereby confirming the Jsup(π)=7/2^- assignment to the level. (author)
