Tidskriftsartikel (refereegranskat)abstract
- The angular momenta and parities of the low lying states of Sn-132 have been firmly determined through studies of the beta-decay of In-132. The lowest lying state with a negative parity is shown to have a collective octupole character. Several particle-ho

Tidskriftsartikel (refereegranskat)abstract
- The structure of Ra-229 has been studied in the beta(-) decay of Fr-229. Spins and parities have been determined from the conversion electron measurements, while half-lives for the 137.5, 142.7, 168.8, 213.0 and 479.0 keV levels have been measured in the

Tidskriftsartikel (refereegranskat)abstract
- The location of several single-neutron states in Sn-133 has been identified. The P-3/2, h(9/2), and f(5/2) states were found at 853.7, 1560.9, and 2004.6 keV, respectively, by measuring gamma rays in coincidence with delayed neutrons following the decay o
