Abstract : Approximately forty levels in 37K have been established via various nuclear reactions. Measurements of capture-gamma-ray energies with Ge(Li) counters have made possible the determination of several level energies with precisions ranging from 1 to 5 keV. The analogues in 37K of the first two excited levels in 37Ar were found as a closely spaced doublet at 1368 and 1380 keV excitation energy. The half-life of the latter has been measured electronically to be 9.6 plus or minus 1.4 nsec. The energies (in keV), spins, and parities of the lowest eight levels are given. Spin and parity assignments to other levels are also presented. Approximate values for the elastic and inelastic proton and gamma-ray widths of several levels have been determined. Evidence regarding the spins, parities, and widths of two candidates for the lowest T = 3/2 level is presented. The Q-value for 36Ar(p, gamma) is 1857.0 plus or minus 1.4 keV and the mass excess of 37K on the 12C = 0 scale is - 24799.6 plus or minus 2.7 keV.
