    "abstract": "We present progress towards a planned experiment on atomic tunneling of\nultra-cold Rb atoms. As a first step in this experiment we present a\nrealization of an improved form of \"delta-kick cooling.\" By application of a\npulsed magnetic field, laser cooled Rb atoms are further cooled by a factor of\n10 (in 1-D) over the temperature out of molasses. Temperatures below 700 nK are\nobserved. The technique can be used not only to cool without fundamental limit\n(but conserving phase-space density), but also to focus atoms, and as a\nspin-dependent probe.",
