By means of in-beam gamma-ray and conversion electron spectroscopy spin and parity has been assigned to states of 97,99Mo observed in the 96Mo(d,pγ)97Mo and 98Mo(d,pγ)99Mo reaction, respectively. The data indicate that no low-spin negative parity states are likely to exist below ∼ 1 Mev.

Gamma-ray and internal conversion studies of the odd Sn isotopes investigated through (α,n) and (d,p) reactions are reported. A level scheme is proposed for each nucleus. An odd parity state at moderate excitation energy above the 1h 11/2 single quasiparticle state is identified or proposed in each nucleus, some of which are observed for the first time. Individual level structure and the level systematics in the odd tin isotopes are discussed.

An in-beam study of excited states in 115Sn has been made through the reactions 115In(p,n)115Sn, 112Cd(α,n)115Sn, 115In(d,2n)115Sn, and 113Cd(α,2n)115Sn. A level scheme containing 21 levels is proposed on the basis of the following measurements: γ-ray energies and intensities, excitation functions, conversion electron intensities, γ-γ- and e-γ-coincidences and angular distribution of γ-rays. The position of an odd parity state above the h11/2- single particle state is discussed.
