Abstract:	Theβ ^? decays of¹⁰³Nb and¹⁰⁵Nb have been studied at the fission product separators JOSEF and LOHENGRIN. Half-lives of (1.5±0.2) s and (2.95±0.06) s, respectively, have been determined for these decays. Fromγ singles andγ-γ coincidence measurements extended level schemes for¹⁰³Mo and¹⁰⁵Mo have been established for the first time. The lowest energy levels of these nuclei are consistent with the interpretation as members of rotational bands built on a 3/2⁺ 411] Nilsson state. Evidence is presented for the location of the 9/2⁺ 404] configuration.
