Abstract

An effusive thermal molecular beam of CaCI was produced vapourizing a mixture of Ca and CaCI2 within a crucible with subsequent expansion into vacuum. Lifetimes of CaCl(A2Π) in its two lowest vibrational levels were measured under collision-free conditions using laser-induced fluorescence, and values around 33 ns are found; these are discussed with respect to other available data.
