Commissioning of the DIAMANT 'Chessboard' Light-Charged-Particle CsI Detector Array with AFRODITE
Abstract
In a commissioning measurement, the 'Chessboard' section of the DIAMANT charged-particle array has been coupled with the AFRODITE {gamma}-ray spectrometer at the iThemba Laboratory for Accelerator Based Sciences. Two data-sets were obtained following the bombardment of a 170Er target with a 13C beam at energies of 80 and 70 MeV, respectively. Offline analysis has thus far enabled the extension of a number of rotational bands associated with high-K intrinsic states in 176Hf. Also, the A = 172, 173 and 174 stable isotopes of ytterbium were populated via 2{alpha}xn channels with strengths of {approx}30-to-40% of the {alpha}xn yields. This, together with the comparative weakness of the pxn channels, is consistent with incomplete fusion as the dominant reaction mechanism responsible for the {alpha}-particle emission.
