In-beam γ spectroscopy of 34Si with deuteron inelastic scattering using reverse kinematics -: art. no. 064315

Excited states of Si-34 were studied in the H-2(Si-34, Si-34 gamma) reaction using a radioactive Si-34 beam at 38.4A MeV and a liquid deuterium target. Deexcitation gamma rays were measured using a NaI(Tl)-scintillator array in coincidence with scattered Si-34 particles. From gamma-gamma coincidence analyses, the gamma lines at 1.193, 1.715, and 2.696 MeV, which were reported previously but unplaced in the level diagram, were found to be associated with the 3.326-MeV gamma line corresponding to the transition from the first 2(+) state to the ground state. This excludes the 1.193-MeV line as a candidate for the transition from the 2(+) state to the second 0(+) state, as suggested by Nummela et al. [Phys. Rev. C 63, 044316-2001)].
