    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 Gamma-ray measurements have been performed on biofuel samples using a planar intrinsic Ge detector. The samples were first homogenized and then packed into 90 ml plastic tubs. The radiation from each sample was usually measured for 1 to 2 days. The intensity of the 63.3 keV γ-ray in234Th was used to determine the amount of238U present. The amount of235U can be determined from the intensity of the 143.8 keV γ-ray.

    Notes: Abstract Low-volume samplers collecting ambient aerosols in two size fractions have been used to collect radioactivity from the Chernobyl accident. The samplers were situated near light-houses on the east coast of Sweden and samples were collected during consecutive 12-hr periods. Activity concentrations of 95Zr, 95Nb, 103, 106Ru, 131I, 134, 136, 137Cs, 140Ba, 140La, 141,144Ce, and 239Np were measured with a Ge(Li) detector. The transportation time between Chernobyl and the two sampling sites is in good agreement with times calculated from air mass trajectories. The main part of the radioactivity was found on particles with an aerodynamic diameter of less than 2 μm.
