The ground-state rotational band of 232U is established up to Iπ = 16+ (tentatively 18+) through a study of the 232Th(α, 4nγ) reaction. Conversion electron spectroscopy is found to be especially useful in circumventing the difficulties caused by s

Ground-state band members up to Jπ = 10+ in 100Ru and up to 14+ in 150Sm and odd-spin negative parity states up to 15− in both nuclei have been identified from (α, 4n) in-beam γ-ray and conversion electron spectra. The data are interpreted in te

Several new high-spin (I>10) isomeric states in the mass region A=144–164 are located in a systematic search with 12C induced reactions, employing a sixteen NaI (Tl)Ge(Li) detector multiplicity filter. The proximity to the N=82 neutron shell clo

Axions, if existing, can cause a strong signal of positron-electron pairs in isoscalar M1 transitions in competition with gamma-ray emission. We searched for such a signal in the 3.59 MeV transition in 10B with a fourfold Mini-Orange spectrometer. No

Regular patterns of E0 transitions were observed after 232Th(α,xn reactions. They indicate that the moments of inertia of β- and ground-state bands are nearly equal in 234U, in contrast to its even-even neighbours 232Th, 232U and 236U.

The 150Nd(α, 4n) reaction at Eα = 45 MeV has been used to study high spin states in the 15062Sm88 nucleide. The experiments comprised measurements of singles γ-ray and conversion electron spectra, γ-ray angular distributions, three-parameter (Eα

To identify the residual nuclei in very asymmetric heavy-ion reactions heavy-ion K X-ray coincidences have been measured. The usefulness and limitations of this method are discussed, and its feasibility is demonstrated in a study of the 14N+197Au rea

The high-spin level structures of 152 Dy and 153 Dy were studied experimentally with 154, 155 Gd(α xnγ ) in-beam reactions, and for 152 Dy also with 144, 146 Nd ( 12 C, x n γ) reactions. The experiments included measurements of singles γ-ray and
