Measurement of branching ratios of low energy deuteron-induced nuclear reactions on [sup 2]H, [sup 6]Li, and [sup 10]B

We have measured the branching ratios [sup 2]H([ital d],[ital p])[sup 3]H/[sup 2]H([ital d],[ital n])[sup 3]He, [sup 6]Li([ital d],[ital p])[sup 7]Li/[sup 6]Li([ital d],[alpha])[sup 4]He, and [sup 10]B([ital d],[ital p])[sup 11]B/[sup 10]B([ital d],[alpha])[sup 8]Be between c.m. energies of 3 and 15 keV, 20 and 135 keV, and 58 and 142 keV, respectively. Our measurements of the [sup 2]H-[ital d] reaction are in good agreement with [ital R]-matrix calculations of the branching ratio. We find no enhancement of the ([ital d],[ital p]) branches of these reactions at the lowest observed energies. Implications of our findings to recent claims of anomalous production of heat from deuterium-metal systems are presented.
