Description

Recently, a new technique to determine lifetimes of excited states from a few to hundreds of femtoseconds has been established in Cologne: the Doppler-shift attenuation method (DSAM) using pγ coincidences. The SONIC rate at HORUS setup with its 14 HPGe detectors and several silicon detectors enables to extract the centroid-energy shifts from proton-gated γ-ray spectra, yielding lifetime values that are independent of feeding contributions. This contribution introduces this (p,p'γ) DSAM technique and show the results of measurements on 96Ru, 98Ru, 112,114Sn, and 94Zr.
