Abstract
We have trapped 40K 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 approximately equal to} 108 atoms/cm3. Contrary to what observed for the other isotopes of potassium, our data indicate that temperatures lower than the Doppler-cooling limit can be reached for 40K. We discuss the interest of these results in view of possible experiments to study a degenerate Fermi gas.Citation
