[en] Levels of 191Pt populated in the decay of 3.2h 191Au have been investigated by γ-ray singles and comprehensive γ-γ coincidence measurements. A detailed 191Au decay scheme, which differs radically from earlier versions, has been established. The 191Au decay results are discussed with reference to those obtained in complementary (α, 3nγ) studies of odd-A Pt nuclei and with particular emphasis on the locations and properties of low-spin members of the γisub(13/2) level family in 191Pt.

[en] The decay of 1.83 day 48Sc and 16.2 day 48V were investigated to resolve discrepancies in the literature concerning the level properties of 48Ti. The decay of 48Sc populates levels at (log ft in parenthesis) 983.512(-), 2295.618(-), 3333.13 (5.52) and 3508.48 keV (5.99). The 48V populates levels at 983.512(-), 2295.618 (6.30), 2420.8(-), 3223.92 (6.64), 3239.73 (6.26) and 3359.5 keV (9.0). (author)
[en] The threshold for the 34S(p, n)34Cl reaction has been measured and the reaction Q-value determined to be -6274.27 +- 0.56 keV. From this the Q-value for the 34Cl superallowed β-decay has been deduced as 4469.8 +- 0.6 keV, which is in good agreement with other recent measurements. Using the presently accepted value for the 34Cl half-life, the ft value has been calculated to be 3085.1 +- 3.8 s. (Auth.)
[en] Levels in 186Os populated in the decay of 1.7-h 186Ir have been studied by high-resolution γ-ray singles and γ-γ coincidence spectroscopy. Many γ rays have been assigned to this decay and several new levels in 186Os have been established. On the basis of the observed decay properties and level systematics, a spin-parity assignment of 2- and the Nilsson configuration ]3/2 + π, 7/2 - νclosing-brace are suggested for 1.7-h 186Ir
[en] The half-life of 38Km has been measured to be 924.46(14) ms, a result that is a factor of two more precise than any of the five previous measurements of this quantity. The previous results are not consistent with one another, but our result agrees well with the two most recent ones. The derived ft value for 38Km is now one of the three most precisely known superallowed ft values.
