Abstract

The Doppler Shift Attenuation Method is a technique to measure lifetimes of excited states in the range of fs up to ps. The energy of the Doppler shifted γ-ray, which is emitted by a decelerating excited nucleus, is measured with a HPGe detector. The Doppler shifted γ-ray energy spectrum can then be used to extract the lifetime. The experimental astrophysics group at TU Munich is building such a facility to measure the lifetimes of excited states of astrophysical interest. These data will provide information required for calculating resonant proton capture reaction rates and, therefore, can be used for network calculations to predict the elemental abundances of e.g. nova explosions. First tests and experiments are planned in 2010.
