Abstract
Mass separated, neutron rich and isotopes were studied. 1565 0 Singles gamma and conversion electron spectra following the β- decay of these nuclei were investigated using Ge(Li) and Si(Li) detectors, respectively. Gamma ray and internal conversion electron relative intensities are listed, and spin and parity assignments, based on transition multipolarities, are proposed. Results are compared with earlier measurements. Some evidence for an isometric state in 143Ba is presented.
