We present results of the study of a simultaneously confined metastable helium (He*) and rubidium magneto-optical trap (MOT). By monitoring the trap decay of the Rb-87 MOT with and without a He* MOT present, we find the light-assisted, two-body loss rate to be beta(Rb-He)* = (6 +/- 2) x 10(-10) cm(3)/s. Moreover, we find that it is possible to create a large, robust Rb-87-He* MOT, opening the possibility of creating a Rb-87-He* Bose-Einstein condensate. This would be the first dual-species condensate incorporating an alkali metal ground-state atom and an excited-state noble gas atom.
