    Notes: Abstract Isomeric cross-section ratios have been measured for the reactions107Ag(α,2n)109g,mIn and109Ag(α, 2n)111g,mIn for energies of theα-particles between 19 and 40 MeV. The experimental isomeric cross-section ratios are compared with statistical-model calculations. The program ofHafner et al. was extended by including the competition of the (α,n)- and (α, 3n)-reactions and of charged particle emission. Agreement between experiment and theory could be achieved.

    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.

    Suche nach dem Einfluß der chemischen Bindung auf die Halbwertszeit des90m Nb (T 1/2=19,2 sec) (1968)

    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.
