Abstract

Flowing and stationary afterglow experiments were performed to study the recombination of D3+ ions with electrons at temperatures from 77 to 300 K. A linear dependence of apparent (effective) binary recombination rate coefficients on the pressure of the helium buffer gas was observed. Binary (D3+ + e-) and ternary (D3 + + e- +He) recombination rate coefficients were derived. The obtained binary rate coefficient agrees with recent theoretical values for dissociative recombination of D3+. We describe the observed ternary process by a mechanism with two rate determining steps. In the first step, a rotationally excited long-lived neutral D3 is formed in D3+ - e- collisions. As the second step, the D3 collides with a helium atom that prevents autoionization of D 3. We calculate lifetimes of D3 formed from ortho-, para-, or metastates of D3+ and use the lifetimes to calculate ternary recombination rate coefficients.
