    Notes: Abstract The gamma-ray decay of the 1658 keV resonance, which is a member of the isobaric analogues of the 1904 keV 3/2− level in44Ca, has been studied with a Ge(Li) detector. A number of gamma-ray transitions are described and associated with the decay of 15 levels between 1.50 and 3.05 MeV. These observations have made it possible to deduce spin and parity assignments to some of the levels. By comparing excited levels of43Sc and45Sc it has been possible to assign certain levels as members of one negative-parity band and two positive-parity bands withK π=1/2+ and 3/2+.

    Notes: Abstract The50Cr(d, n)51Mn and54Fe(d, n)55Co reactions have been studied at an incident deuteron energy of 5.5 MeV. Angular distributions of neutron groups to a number of low-lying levels in the residual nuclei have been recorded. Time-of-flight techniques have been used to record neutron spectra. A liquid scintillator with pulse-shape discrimination property has been used as neutron detector. DWBA calculations have been performed and relative spectroscopic strengths determined for transitions with variousl p values. The ratios between spectroscopic strengths forl p =3 andl p =1 transitions were found to be considerably larger than corresponding ratios obtained from the (3He,d) reactions. Two-step stripping processes competing with the direct stripping process are suggested as explanation of the discrepancy between the (d, n) and the (3He,d) results.

    Notes: 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.
