Energetic protons and α particles emitted in 150-keV deuteron bombardment on deuterated Ti

Energetic charged particles have been measured in the bombardment of 150-keV deuterons on deuterated Ti. Protons and α particles were observed with energies up to ∼17 and ∼6.5 MeV, respectively, which can never be attained in the D+D reaction. A bump structure at around 14MeV seen in the proton spectrum can be well explained as emitted in the sequential reaction involving three deuterons. However, protons and α particles distributed continuously up to the maximum energies can never be understood as products of the conceivable nuclear reactions.
