Abstract: We have trapped K-40 in a vapor-cell magneto-optical trap starting from a natural abundance sample. This rare, weakly radioactive atom is a fermion. The number of trapped atoms is approximately 8000, with a density of similar to 10(8) atoms/cm(3). Contrary to what is observed for the other isotopes of potassium, our data indicate that temperatures lower than the Doppler-cooling limit can be reached for K-40. We discuss the interest of these results in view of possible experiments to study a degenerate Fermi gas. [S1050-2947(98)05601-7].
