Lifetime measurements in 96Zr using the Coincidence Doppler-Shift Attenuation Method — •Elias Binger, Anna Bohn, Sarah Prill, Tobias Langel, Michael Weinert, and Andreas Zilges — University of Cologne, Institute for Nuclear Physics, Germany
The Coincidence Doppler-Shift Attenuation Method (CDSAM) [1,2] is a technique for determining nuclear level lifetimes in the sub-picosecond range. Using the SONIC@HORUS [3] setup at the University of Cologne, the Doppler-shifted γ rays can be detected in coincidence with the scattered beam particles, enabling background reduction, precise transition selection and feeding exclusion.
As part of a series of lifetime measurements in the mass region A=100, a (p,p’γ) experiment was performed on 96Zr. Through the analysis of the recorded data, the lifetimes of many excited states could be determined. The results of this experiment are presented in this contribution.
