Lifetime determination of excited states in 104Ru and 130Te via a new Doppler-shift attenuation approach

The Coincidence Doppler-shift attenuation method (CDSAM) after proton scattering is a well-established technique for determining nuclear-level lifetimes in the range of sub-picoseconds. In recent years, several (p,p'γ) experiments have been performed utilizing the combined detector array SONIC@...

description The Coincidence Doppler-shift attenuation method (CDSAM) after proton scattering is a well-established technique for determining nuclear-level lifetimes in the range of sub-picoseconds. In recent years, several (p,p'γ) experiments have been performed utilizing the combined detector array SONIC@HORUS consisting of 14 HPGe detectors and 12 silicon detectors. To complement the well-established analysis procedure, a reverse method was tested. A first benchmark analysis was conducted on 130Te, showing good agreement. Furthermore, spectroscopy and level-scheme construction are feasible due to the coincidence conditions enabled by γ- as well as particle-detection using SONIC@HORUS. Preliminary results on 104Ru obtained by inelastic proton scattering and the fundamental principles of the reverse approach benchmarked on 130Te, will be presented.
