[en] Angular distribution coefficients for γ rays from the ¹⁰⁹Ag(α,nγ)¹¹²In reaction at 16.4 MeV are tabulated. A partial level scheme with J/sup π/ assignments is given. The nuclear structure of ¹¹²In is discussed briefly. 1 figure, 1 table

[en] The ⁸⁹Y(α,3nγ)⁹⁰Nb reaction was studied at 35.7 MeV. The location of the 9⁺ member of the π(g/sub 9/2/ν(g/sub 9/2/)^-1 multiplet was clarified, and two previously unobserved higher-spin states were found. A partial level scheme with spin--parity assignments is exhibited. 1 figure

[en] Experimental triton spectra and angular distributions from the ⁹⁰Zr(³He,t)⁹⁰Nb reaction at 43.4 MeV are presented. The j dependence of the angular distributions enabled J/sup π/ assignments to be made. 3 figures, 1 table

[en] The ⁸⁹Y(α,2nγ)⁹¹Nb reaction was studied at 24.0 and 35.7 MeV. Results of γ data are presented in a level scheme; spin--parity assignments are made; and the structure of ⁹¹Nb is discussed briefly. 1 figure

[en] A sample spectrum from the reaction at 43 MeV is shown, and relative strengths are compared with those of other reactions exciting the same states. 1 figure, 1 table

[en] Typical coincidence gamma spectra from the ⁹⁰Zr(³He, 3nγ)⁹⁰Mo reaction at 33 MeV are shown. Level schemes obtained from this reaction (and the (³He,4nγ) reaction) are presented and discussed. 3 figures

[en] Levels populated by the ⁸⁴,⁸⁶Sr(α,2nγ)⁸⁶,⁸⁸Zr reactions and the ⁸⁴Sr(α,nγ)⁸⁷Zr reaction were studied at bombarding energies of 16.7 to 35 MeV. Also levels in ⁸⁸Zr populated by the ⁸⁹Y(p,2nγ) reaction were studied at 22.7 MeV incident proton energy. The g-factor of the 8⁺ state at 2887 keV in ⁸⁸Zr was also measured with the latter reaction using the perturbed angular correlation technique. A number of new high spin states in ⁸⁸Z and ⁸⁷Zr were observed, and a level scheme for ⁸⁶Zr was obtained for the first time. The levels observed were interpreted within a shell model context. Spins, parities, multiplets, transitions, and level structure and kinetics are discussed. 10 references

[en] The 33 MeV ₈₆Sr(₃He,3nν) reaction has been used to re-measure the level structure of the N=46 nucleus ₈₆Zr. The lowest 8⁺ level is found at 3,297.5 keV, consistent with some but not all earlier studies. On the basis of spectroscopic measurements and data-to-data comparisons with other N=46 nuclei, the 3,531.8 keV level is also suggested as an 8⁺. (orig.)

[en] The structure of ⁹²Nb has been investigated using the 33.8 MeV ⁹²Zr(³He,t) and (³He,p2nγ) reactions. Several previously unobserved levels, including several belonging to the π(gsub(9/2))ν(gsub(9/2))^-1 multiplet, are reported. The results are discussed in terms of the shell model. (orig.)

[en] The structure of the N = 48 nucleus ⁸⁹Nb has been studied using in-beam γ-ray spectroscopy following a number of reactions. Several levels with spins between 15/2 and 25/2 are identified. The results are discussed in terms of the shell model. (orig.)
