TiH2 and TiD2 thick targets were bombarded with 100 to 200 keV protons. Evidence for nuclear reactions was obtained by means of a surface barrier particle detector. Proton irradiation of TiD2 produced the following observations: α particle emission identified as (p,α) reactions from 11B and 7Li impurities in the target at ppm concentrations; and ∼3 MeV proton and ∼1 MeV triton emission from secondary D-D reactions caused by elastic scattering of the primary proton with a target deuteron. A 3.9 MeV α particle peak measured by others was not observed.
