Abstract
Atomic europium has been magnetically trapped using buffer-gas loading . Laser ablated Eu(S-8(7/2)) atoms are thermalized to 800 mK in a He-4 buffer gas (to 250 mK in a He-3 buffer gas). Anti-Helmholtz supercond ucting coils produce a quadrupole magnetic field to trap the M-J=7/2 s tate of Eu. Detection is via absorption spectroscopy at 462.7 nm. Up t o 1x10(12) Eu atoms are loaded at a central density of 5 x 10(12) cm(- 3). Atoms can be held for longer than 100 s.
