Abstract

The charged particle spectra from the deuteron bombardment of Be9 have been analyzed magnetically with a spectrograph employing a second-order focus. Previously established transitions to states in Be10 and Li7 were observed, and a careful search of the proton and alpha-spectra failed to disclose additional states in these nuclei, throughout the region explored. The excitation energy of the second excited state of Li7 was determined as 4.62±0.02 Mev. The transition to the broad first excited state of Be8, as well as to the ground state, was revealed in the triton spectrum. Alpha- and triton continue resulting from the three-particle disintegrations, Be9(d, α)Li7**(α)t and Be9(d, t)Be8*(α)α, were also observed and examined in some detail. Other three-particle disintegrations appear improbable but cannot be definitely excluded, at the bombarding energies employed from 0.5 to 1.0 Mev.
