    Notes: Abstract 79 mBr was produced by irradiation of natural Br with fast neutrons. The half-lifeT 1/2=(4.87±0.15) sec and the energyE γ=(208±1) keV were remeasured. For the first time the conversion coefficients were determined to beα K=0.25±0.02 and αtotal=0.28±0.05, yielding the multipolarityE3 for the isomeric transition.

    Notes: Abstract 90m Nb was produced by the reaction90Zr(d, 2n). Comparison of its half-lives in two different chemical environments (Nb atoms in metallic Zr and in the niobium-fluoride complex) showed no difference greater than the experimental error of 1%, whileCooper et al. have reported that the half-life of90m Nb nuclei is shorter by 3.6% in metallic Nb than in the niobium-fluoride complex. — In addition, the absolute value of the half-life of90m Nb in metallic Zr was determined to beT 1/2=(19.2±0.3) sec.

    Notes: Abstract Theγ spectra emitted in the decay of122Xe and122I have been investigated using Ge(Li) detectors and a Ge(Li)-NaI coincidence apparatus. 14γ transitions with energies between 61.8 and 416.9 keV have been identified in the decay of122Xe, 44 transitions between 564.0 and 3,291.0 keV in the decay of122I. Level schemes having 7 excited levels for122I and 21 excited levels for122Te are proposed.

    Notes: Abstract Tl197m was produced by the (α, 4n) reaction on Au197 using 49 MeVα particles. The following results were obtained: Half-lifeT 1/2=(0.55±0.02) sec; energy of the isomeric level (607±4) keV, determined directly by summing up the cascade transitions in a well-type scintillator; energy of the isomeric transition (222±2) keV; conversion coefficients of this transitionα K222=0.41±0.05 andα tot222=2.1±0.2, indicating anE3 multipolarity; energy of the second transition (385±3)keV; conversion coefficientsα K385=0.09±0.03 andα tot385〈0.1. This transition was identified asE2 with aM1 admixture of 20 to 30%. Spins and parities are 1/2+, 3/2+ and 9/2− for the ground state, the 385 keV state and the 607 keV isomeric state, respectively, in disagreement with the extreme single-particle model. If this model were correct, anotherM1 transition should appear. No furtherM1 transition having an energy greater than theL-shell binding energy of T1 was observed.

    Notes: Abstract An activity with the decay propertiesT 1/2=(8.0±0.3)sec andE γ=(283±5)keV has been produced bySchardt andGoodman by proton irradiation of thin layers of evaporated73Ge and74Ge on thick gold backings. This activity was interpreted as the new isomer74mAs. In the present experiment a search for74mAs was carried out using the reactions75As(n, 2n),71Ga(α, n) and74Ge(d, 2n).74mAs could not be detected. Upper limits for the reaction cross sections were determined. It is discussed that the reported properties of74mAs resemble the known properties of197mAu.

    Der Zerfall des125m Xe, des127m Xe und des127g Xe (1968)

    Notes: Abstract The decay of125m Xe produced by the reaction122Te(α, n)125m Xe using a target enriched in122Te (95.4%) and the decay of127m Xe produced by the reaction127J(d, 2n)127m Xe have been investigated: 125m Xe decays with a half-life ofT 1/2=(56±3) sec by ayy- cascade withE γ1=(140.4 ±0.5) keV andE γ2=(110.5 ±0.5) keV. The experimental conversion coefficients yield multipolarities ofE3 for the 140.4 keV isomeric transition and predominantlyM1 for the 110.5 keV-transition. 127m Xe decays with a half-life ofT 1/2=(71±2) sec. The decay also proceeds by aγγ-cascade with an isomeric E3 transition ofE γ1=(172.5±0.3) keV and a predominantlyM1 transition ofE γ2=(124.6±0.3) keV. In the decay of127g Xe an additional branching of the electron capture to a level at (618.1±0.3) keV was observed. The relative probability forK-captureP K618/PK375=0.40 ±0.07 yields a total transition energyQ EC=(664 ±4)keV. A spin of 1/2+ was assigned to the ground state.
