The density of accessible levels at low spin in the ( ${}^{3}\mathrm{He},\ensuremath{\alpha}\ensuremath{\gamma}$) reaction has been extracted for the ${}^{162}\mathrm{Dy}$, ${}^{166}\mathrm{Er}$, and ${}^{172}\mathrm{Yb}$ nuclei. The nuclear temperat

The intensities of primary {gamma}-ray transitions following thermal and average resonance neutron capture have been found to display a dependence on the final-state K quantum number. The apparent K-hindrance effect is significantly stronger in the t

A new method for unfolding γ-ray spectra is described. The method is based on the fact that the contribution of Compton scattered γ-rays in the spectra is a slowly varying function of energy. Thus, the Compton part can be smoothed and subtracted fr

The level density of low-spin states (0–10ħ) in 162Dy has been determined from the ground state up to approximately 6 MeV of excitation energy. Levels in the excitation region up to 8 MeV were populated by means of the 163Dy(3He,α) reaction, and

Neutron capture resonances produced in {sup 177}Lu by thermal neutrons are shown to gamma decay with intensities which are dependent on a {Delta}{ital K} selection rule. The difference between {Delta}{ital K}- forbidden (and {Delta}{ital K}-allowed)

The α-particle energy distributions from the 163 Dy( 3 He ,αx n γ) reactions with E(3He) = 45 MeV have been studied. The α-particles populating 158–162Dy have been selected by setting gates on the yrast transitions in the respective isotopes. A

The statistical γ-ray multiplicity distributions following the reactions 163 Dy( 3 He ,αx n ) 162−x Dy and 173 Yb( 3 He ,αx n ) 172−x Yb have been studied. The mean value 〈 M 〉 and standard deviation σ M have been extracted as functions o

The light output and energy resolution for the scintillators CsI(Tl), YAG(Ce), GSO(Ce), BGO and LSO(Ce) have been measured with 1H, 2H and 3He ions in the energy region ∼ 3–20 MeV/nucleon using photodiodes for the light readout. A very good energ

The energy-corrected intensities of the primary [gamma] transitions in [sup 166]Ho following thermal and average resonance neutron capture are calculated from data available in the literature. The [gamma] decay of this odd-odd nucleus shows the same

The γ-rays emitted after the 163 Dy ( 3 He ,αx n ) reactions at E( 3 He ) = 45 MeV have been measured. The transferred angular momentum in the reaction is deduced from the side-feeding γ-intensities of the ground bands in the residual 162−xDy is
