State Specific Stabilization of H+ + H-2(j) Collision Complexes

Popis výsledku v původním jazyce

Stabilization of H-3(+) collision complexes has been studied at nominal temperatures between 11 and 33 K using a 22-pole radio frequency (rf) ion trap. Apparent binary rate coefficients, k* = k(r) + k(3)[H-2], have been measured for para- and normal-hydrogen at number densities between some 10(11) and 10(14) cm(-3). The state specific rate coefficients extracted for radiative stabilization, k(r)(T-ij), are all below 2 x 10(-16) cm(3) s(-1). There is a slight tendency to decrease with increasing temperature. In contrast to simple expectations, k(r)(11 K-ij) is for j = 0 a factor of 2 smaller than for j = 1. The ternary rate coefficients for p-H-2 show a rather steep T-dependence; however, they are increasing with temperature. The state specific ternaryrate coefficients, k(3)(T-ij), measured for j = 0 and derived for j = 1 from measurements with n-H-2, differ by an order of magnitude. Most of these surprising observations are in disagreement with predictions from standard association mo
