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 σ_elequals(1.5±0.6)×10^-14cm². A lower bound of Γ_rotational⩾10^-15cm³s^-1 was placed on the rotational elastic collision rate coefficient, and an upper bound of Γ_ν<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.
