Abstract

The particle spectrometer SONIC for particle-gamma coincidence measurements was commissioned at the Institute for Nuclear Physics in Cologne, Germany. SONIC consists of up to 12 silicon Delta E-E telescopes with a total solid angle coverage of 9%, and will complement HORUS, a gamma-ray spectrometer with 14 HPGe detectors. The combined setup SONIC@ HORUS is used to investigate the gamma-decay behaviour of low-spin states up to the neutron separation threshold excited by light-ion inelastic scattering and transfer reactions using beams provided by a 10MV FN Tandem accelerator. The particle-gamma coincidence method will be presented using data from a 92Mo(p, p'gamma) experiment. In a 119Sn(d, X) experiment, excellent particle identification has been achieved because of the good energy resolution of the silicon detectors of approximately 20 keV. Due to the non-negligible momentum transfer in the reaction, a Doppler correction of the detected gamma-ray energy has to be performed, using the additional information from measuring the ejectile energy and direction. The high sensitivity of the setup is demonstrated by the results from a 94Mo(p, p'gamma) experiment, where small gamma-decay branching ratios have been deduced. (C) 2017 Elsevier B.V.
