Abstract

We report on the production, deceleration and detection of a SrF molecular beam. The molecules are captured from a supersonic expansion and are decelerated in the X2Σ+(v=0,N=1) state. We demonstrate the removal of up to 40% of the kinetic energy with a 2m long modular traveling-wave decelerator. Our results demonstrate a crucial step towards the preparation of ultracold gases of heavy diatomic molecules for precision spectroscopy.
