High spin states in105Ag

Levels in105Ag were populated by the103Rh(α, 2nγ) reaction,γ-singles spectra,γγ-coincidences, excitation functions, angular distributions and polarisation measurements were taken. These measurements were used to construct a level-scheme and give various spin and parity assignments.Nuclear Reactions:103Rh(α, 2nγ)105Ag; measuredEγ, Iγ, γγ-coincidences, excitation functions, angular distributions, polarisation.

High spin states in77Se populated by the74Ge(α,n γ) reaction

Abstract77Se has been investigated by the reaction74Ge(α,nγ) at 14 MeV. Gamma singles spectra, gamma angular distributions and gamma-gamma coincidences have been taken. A level scheme has been established, spins and parities have been assigned. States of a rotational band on the 1/2− ground state, a rotational band on the 5/2− 249.7 keV state and an anormal band have been identified. Nuclear Reaction74Ge(α,n γ)Eα=14 MeV; measuredEγ,Iγ,γ-γ-Coin.,γ-ang. distr.77Se deduced levels,J, π. Enriched target, Ge (Li).

High-spin states in99Tc

The level scheme of99Tc was studied byγ-ray spectroscopy with the96Zr(6Li, 3n γ)99Tc reaction. New levels were established and spins and parities assigned.99Tc is compared with93, 95, 97Tc, with the neighbouring even-even Mo-isotopes and with the results of an IBFM calculation.

High-spin states in 52Cr populated via the 50Ti(α, 2nγ) reaction

Abstract The decay scheme of 52 Cr has been studied by γ-ray spectroscopy with the 50 Ti( α , 2n γ ) reaction. Spin and parity assignments were made on the basis of coincidence measurements, angular distributions, excitation functions and DSAM lifetime measurements. Six new high-energy levels with spins up to 9 were established.

High spin states in95Tc populated in the93Nb(α, 2nγ) reaction

The93Nb(α, 2nγ)95Tc reaction has been studied at a bombarding energy of 22.5 MeV using Ge(Li)-detectors. Gamma singles spectra, gamma-gamma coincidences, excitation functions and gamma angular distribution have been obtained. A level scheme has been constructed. Spin and parity assignments up to 29/2+ are given.

High-spin states in97Tc

The level scheme of97Tc was studied by gamma ray spectroscopy using the94Zr(6Li, 3nγ)97Tc reaction. New levels and spins and parities were established.97Tc is compared with the neighbouring even-even nucleus and with the results of an IBFM calculation.

High spin states in107Ag

Abstract107Ag hasbeen investigated by the reactions104Ru(6Li, 3nγ) and104Ru(7Li, 4ny). γ-singles spectra,γ-γ-Δt-coincidences,γ-angular distributions and polarization measurements were taken. A level scheme has been established, spins and parities have been assigned.
