Abstract: | The level scheme of91Nb has been investigated with the reaction90Zr(p, γ)91Nb. Proton energies between 3.0 and 7.2 MeV were used. The γ spectra were taken with Ge(Li) detectors. Primary γ transitions to 36 excited states of91Nb up to 3.8 MeV excitation energy and many secondary γ transitions from the decay of those states were observed, leading to an extension of the known level scheme. The proton binding energy for91Nb was determined as (5167± 5) keV. Eleven γ transitions in90Zr, part of them new, from the competing reaction90Zr(p, p′ γ) were also observed. |
