    Notes: Abstract The decay of the isomeric pair83gSe (T1/2=22.6 min,I α = 9/2+) and83mSe (T1/2=70 s,I α = 1/2−) has been reinvestigated using straight Ge(Li) (83gSe and83mSe) and Ge(Li)-Ge(Li) coincidence spectrometry (83gSe). Both decays populate entirely different83Br levels, 11 of them being previously unreported. Fromγ-ray unbalances and from the known isomeric cross-section ratio of82Se, β−-branchings have been obtained, including a 34% branching of83mSe to the ground state of83Br. Logft-values are deduced, spin and parity values proposed and discussed.

    Notes: Abstract The perturbation of the decay constant of90m Nb implanted in various transition metals (Zr, Nb, Hf, Ta, Ag and Au) has been determined by direct half-life measurements. Particular care was taken to evaluate and minimize possible systematic errors. The maximum relative change found is νAu−νNb/νNb=(4.5±0.8)%

    Notes: Abstract Short lived Ru isotopes produced in thermal fission of235U have been chemically separated from the other fission products. Successiveγ-ray spectra were taken by means of Ge(Li) detectors. The observedγ-lines have been assigned to the various Ru isotopes (A=107 to 110) or to their daughter elements on the basis of their half-lives, intensity ratios and known level properties. Partial decay schemes are discussed and relative fission yields are given.111Ru has been identified (T 12: 1.5±0.3 s).

    Notes: Abstract The decay of the 1+, 14 s ground state of116In produced by neutron capture has been reinvestigated using Ge(Li) detectors. It is found that besides the ground state of116Sn, excited levels at 1293.6 (2+), 1756.9 (0+), 2225.3 (2+), 2545.7 (0+, 1+, 2+), 2649.8(2+), 2790.7(2+) and 2844.6(2+) keV are populated, while no evidence could be obtained for the population of the 0+ and 2+ levels at 2030 and 2112.4 keV, respectively. The activation cross-section for116m2In (2.16s,I π = 8−) has been deduced as 83±8 b.

    Notes: Abstract A linear relationship is found between the34S isotopic enrichment factor per pulse and the focal distance of the lens used to concentrate the laser beam. From this, one derives a threshold power of 26 MW/cm2 for photodissociation, a mean absorption of 100 photons of 10.59 μm wavelength per32SF6 dissociation, and a dependence of the enrichment factor on the 3/2 power of the laser pulse energy.
