An initial series of experiments utilising the (3He,n) reactions have been carried out at iThemba LABS. These are complimentary to transfer reactions such as (t,p) stripping or (p,t) pick-up reactions measurements using magnetic spectrometers. Howeve

Shirinda, J.F. Sharpey-Schafer, T. M. Ramashidzha, D.G. Roux, Robert S. Lindsay, Ingemar Ragnarsson, S. M. Maliage
Publikováno v: Physics Letters B. 719:83-88
A pair of rotational bands associated with the pi h(9/2) circle times nu i(13/2)(-1) configuration at lower spins and with the pi h(9/2) circle times nu i(13/2)(-3) configuration at higher spins is found in Tl-194. The two 4-quasiparticle bands show

Publikováno v: Nuclear Physics A. 834:58c-61c
The low-lying, odd-spin negative parity bands in the mass 160 region have been identified as candidates for the rotation of a tetrahedral shape, as they have very weak in-band E2 transitions. We report the observation of such bands in 160 Yb and 154

Characterization of quasiparticle states at and beyond stability in ytterbium isotopes: Spectroscopy of 175Yb, 176Yb and 177Yb

Publikováno v: The European Physical Journal A. 26:265-269
Excited states in 175Yb, 176Yb and 177Yb were populated via the bombardment of a 176Yb target with a 750 MeV 136Xe beam. Gamma-ray decays from these states were measured with the AFRODITE multi-detector spectrometer. The rotational band previously as

Publikováno v: The European Physical Journal A. 50
The high-spin states in 194Tl were studied using the 181Ta(18O, 5n) reaction and the AFRODITE $ \gamma$ -ray spectrometer at iThemba LABS. The level scheme of 194Tl was considerably extended with several new bands. Three negative-parity 4-quasipartic
