Heteronuclear ionizing collisions between laser-cooled metastable helium atoms
J. M. McNamara, R. J. W. Stas, W. Hogervorst +1
We have investigated cold ionizing heteronuclear collisions in dilute mixtures of metastable (2 3S1) 3He and 4He atoms, extending our previous work on the analogous homonuclear col…

Magneto-optical trap for metastable helium at 389 nm
J. C. J. Koelemeij, R. J. W. Stas, W. Hogervorst +1
We have constructed a magneto-optical trap (MOT) for metastable triplet helium atoms utilizing the 2 3S1 -> 3 3P2 line at 389 nm as the trapping and cooling transition. The far-red…
