Abstract
The final-state probability distribution for excitations to the electronic continuum of (HeT+)-He-3 resulting from the beta-decay of T-2 is calculated. The R-matrix method is used to obtain a geometry dependant treatment of the resonance states of (HeT+)-He-3 allowing for nuclear motion effects of these states to be accounted for explicitly in the determination of the final-state distribution. A discretized distribution for the background continuum is used to obtain this part of the decay probability. When combined with previous studies of other energy ranges, 99.94% of the decay probability is recovered, a significant improvement on previous results.
