要旨:
We demonstrate the deceleration of heavy polar molecules in low-field seeking
states by combining a cryogenic source and a travelling-wave Stark decelerator.
The cryogenic source provides a high intensity beam with low speed and
temperature, and the travelling-wave decelerator provides large deceleration
forces and high phase-space acceptance. We prove these techniques using YbF
molecules and find the experimental data to be in excellent agreement with
numerical simulations. These methods extend the scope of Stark deceleration to
a very wide range of molecules.
