Lifetime mearusement of the first excited state in ³¹S with the Doppler Shift Attenuation Method (DSAM) — •Clemens Herlitzius, Shawn Bishop, and Alberto Vesentini — Physik Department E12, TU München, Germany

Measuring lifetimes of excited states of nuclei is important to constrain or estimate resonant (p,γ) capture reaction rates that cannot be determined in a direct measurement, yet are relevant for the production of intermediate mass elements in classical nova events. A new facility has been built and commissioned at the Maier-Leibnitz-Laboratorium (LMU/TUM) that allows to measure lifetimes of states in excited nuclei using the Doppler Shift Attenuation Method. This talk will describe the experimental technique and show data of the beamtime, where the first state in ³¹S has been populated via ³²S(³He,⁴He) in inverse kinematics. The analysis is in process and the status will be presented.
