    "abstract": "We describe a simple experimental technique which allows us to store a small\nand deterministic number of neutral atoms in an optical dipole trap. The\ndesired atom number is prepared in a magneto-optical trap overlapped with a\nsingle focused Nd:YAG laser beam. Dipole trap loading efficiency of 100 % and\nstorage times of about one minute have been achieved. We have also prepared\natoms in a certain hyperfine state and demonstrated the feasibility of a\nstate-selective detection via resonance fluorescence at the level of a few\nneutral atoms. A spin relaxation time of the polarized sample of $4.2\\pm 0.7$ s\nhas been measured. Possible applications are briefly discussed.",
