We report on the efficient generation of cold rubidium atoms as a potential coherent atom source for atom lithography. We successfully trapped and cooled 2.6 × 108 atoms in 5 s with a conventional magneto-optical trap simply by enlarging the diamete

Recent progress in manipulating atoms with laser beams has made it possible to fabricate nanostructures using atom optics. This technique is called atom lithography and is expected to overcome the present technical limitations of conventional lithogr

Natural ${\mathrm{Cd}}^{+}$ ions in a Penning trap are cooled sympathetically below 1 K by a Coulomb interaction with directly laser-cooled ${\mathrm{Be}}^{+}$ ions. Spatial separation of the ${\mathrm{Be}}^{+}$ and ${\mathrm{Cd}}^{+}$ ion clouds due

Two different ion species (Be + and Cd + ) were trapped simultaneously in a Penning trap. The Be + ions were directly laser-cooled and the Cd + ions were sympathetically cooled to below 1 K by the Coulomb interactions. The ultraviolet spectra (5s 2 S
