Paper Abstract

An experiment is described in which 108 CaH molecules have been confined in a magnetic trap at a temperature of 400 mK. The elastic scattering cross section of CaH on 3He was measured to be σelequals(1.5±0.6)×10-14cm2. A lower bound of Γrotational⩾10-15cm3s-1 was placed on the rotational elastic collision rate coefficient, and an upper bound of Γν<10-15 cm3s-1 was placed on the vibrational relaxation rate coefficient. The rate coefficient for spin changing collisions was measured to be, within an order magnitude, Γ Zequals10-17 cm3 s-1.
