    "abstract": "We demonstrate a 1-D velocity selection technique which relies on combining\nmagnetic and optical potentials. We have selected atom clouds with temperatures\nas low as 2.9% of the initial temperature, with an efficiency of 1%. The\nefficiency (percentage of atoms selected) of the technique can vary as slowly\nas the square root of the final temperature. In addition to selecting the\ncoldest atoms from a cloud, this technique imparts a sharp cut-off in the\nvelocity distribution. The cold selected atoms are confined in a small well,\nspatially separated from higher energy atoms. Such a non-thermal distribution\nmay be useful for atom optics experiments, such as studies of atom tunneling.",
