Tidskriftsartikel (refereegranskat)abstract
- The fast timing beta gamma gamma(t) method has been used to measure lifetimes of the low-lying levels in Th-231 populated in the beta(-) decay of Ac-231. The half-life of the K-pi = 5/2(-) band-head at 185.7-keV was measured as T-1/2 = 1073(79) ps, yieldi

Tidskriftsartikel (refereegranskat)abstract
- Spins and parities for collective states in Ra-228 have been determined from conversion electron measurements with a mini-orange beta spectrometer. The fast-timing beta gamma gamma(t) method has been used to measure lifetimes of T-1/2 = 550(20) ps and 181

Tidskriftsartikel (refereegranskat)abstract
- Spectroscopic studies of the beta decay of I-140 have firmly established octupole collectivity in Xe-140 and evinced unique theoretical predictions of a quenched dipole moment. The first detailed investigations of an exotic Xe nucleus, including measureme

-
Tidskriftsartikel (refereegranskat)abstract
- The low-energy structure of the Z=51, N=82 nuclide Sb-133 has been studied through a high-sensitivity investigation of the beta(-) decay of Sn-133. As a result, more than 70 new excited states have been observed and about 100 gamma-ray transitions have be
