The level structure of $sup 137$La populated by the $beta$ decay of $sup 137$Ce/subm/$sup +$/subg/ was studied by $gamma$-ray and conversion-electron spectroscopy using mass-separated sources, large-volume and Compton-suppressed Ge(Li) detectors, and a Si(Li) detector. Nine previously unreported transitions were observed and two more levels were established in $sup 137$La. The $sup 137$La level structure is discussed in terms of the weak-coupling model.
