Abstract
The 2s S-3 + 1s S-1 dissociation threshold of He-2 was probed by means of a technique based on the use of a fast He-2(+) ion beam and charge exchange processes with alkaline vapor. Measurement of the kinetic en ergy spectrum confirmed the known barrier tunneling of the c (3) Sigma (g)(+) state to this dissociation limit and put forth signs of a compe tition between radiative decay and predissociation processes for highl y excited states of He-2.
