    Investigation of65Cu by means of the average resonance proton capture method (1979)
    Springer
    The European physical journal 293 (1979), S. 43-51

    Notizen: Abstract The64Ni(p, γ)65Cu reaction has been studied in the proton energy rangeE p =2.05–2.55 MeV. The gamma-ray spectra were recorded with a three-crystal pair spectrometer at proton energy differences of 19 keV covering the proton energy range. An average gamma-ray spectrum was formed by adding all the individual spectra after proper adjustment as a result of the alterations in proton energy. The intensities of the gamma rays to final states with knownJ π-values were tested against theoretical calculations based on the Hauser-Feshbach theory. The gamma-ray strength function for energies lower than 9 MeV has been extracted from the experiment.

    Excited levels and isobaric analogue states in55Co investigated with the54Fe(p, γ)55Co reaction (1977)
    Springer
    The European physical journal 280 (1977), S. 79-91 
    Details
    ISSN: 1434-601X

    Thema: Physik
    Notizen: Abstract The yield curve for the54Fe(p, γ)55Co reaction in the energy regionE p=1.5–2.9 MeV has been recorded and the decay of ten resonances has been investigated. For six of the resonances the strengths have been determined. The angular distributions of the gamma rays have been recorded for four resonances to obtain spins or spin limitations for excited levels. In addition the lifetimes of 10 bound levels were determined with the Doppler Shift Attenuation Method. The isobaric analogues of the ground state and five excited states in55Fe are discussed.

    Isobaric analogue states excited in the59Co(p, γ)60Ni reaction (1975)
    Springer
    The European physical journal 272 (1975), S. 67-75 
    Details

    Thema: Physik
    Notizen: Abstract The59Co(p, γ)60Ni reaction has been investigated in the proton energy regionE p=1365–2150 keV. Decay schemes and branching ratios have been determined for ten resonances, five of which have been identified as possible analogues or fragments of analogues of the ground state (5+) and the 58.6 keV (2+), 277.1 keV (4+), 288.4 keV (3+), and 435.7 keV (5+) levels in60Co. At eight of the resonances most of the decay seems to go via a group of states with an excitation energy of 5–9 MeV. The investigated analogue states give a Coulomb displacement energy of 9118±7 keV.

    Comparative studies of radionuclides from global fallout and local sources in ground level air and sewage sludge (1983)
    Springer
    Water, air & soil pollution 20 (1983), S. 331-346

    Notizen: Abstract The presence of activation products in the environment released to the air from a nuclear power station has been studied in sewage sludge and ground level air. The measured time variation of the 60,Co concentration in sludge and ground level air was found to be in good agreement with the reported variation in release rate to the air from the power station when the prevalent wind direction is taken into account. The ratio between the 7,Be normalized concentration in sludge and ground level air was studied and was found to be about 1 for radionuclides due to global fallout but less than 2 · 10−3, for 60,Co. Our conclusion is that 60,Co spreads from a local source (a nuclear power station) and to a considerable degree is dry deposited on the ground and then washed off by rain.

    Medically used radionuclides in sewage sludge (1978)
    Springer
    Water, air & soil pollution 9 (1978), S. 199-206

    Notizen: Abstract The concentration of medically used radionuclides has been studied in sludge from the sewage treatment plant serving the borough of Malmo. In this area all nuclear medicine procedures are carried out in one hospital and almost all patients live in the borough. Therefore, the input of medically used radionuclides into the sewage system can be estimated with good accuracy. Samples of digested sludge have been taken once or twice a week during half a year. Iodine-131 (physical half life (T) = R.05 d) was detected in all samples. The 131I-activity concentration due to medical use varied between (0.03±0.01) and (0.12±0.02) nCi kg−1. The ratio between the total output of 131I via the sludge and an adherent input of the radionuclide into the sewage system was determined to (2.6 ± 0.6) × 10−3, which is equivalent to a ratio of (2 ± 1) × 10−2 for stable I. Occasionally measurable activities of 198Au (T=2.7 d) and 201T1(T=3.l d) have been found. The radioactivity concentration of medically used radionuclides in the sludge is low and constitutes no health problems for the persons involved. The sludge however has proved to be a very sensitive and suitable integrator of radioactive material released from a large urban area.
