Excitation functions of 6,7Li+7Li reactions at low energies
Abstract
Differential cross sections of 6,7Li+7Li nuclear reactions have been measured at forward angles (10°and 20°), using particle identification detector telescopes, over the energy range 2.75-10.00 MeV. Excitation functions have been obtained for low-lying residual-nucleus states. The well pronounced peak in the excitation function of 7Li(7Li,4He)10Be(3.37 MeV,2+) at beam energy about 8 MeV, first observed by Wyborny and Carlson in 1971 at 0°, has been observed at 10°, but is less evident at 20°. The cross section obtained for the 7Li(7Li,4He)10Be(g.s,0+) reaction is about ten times smaller. The well pronounced peak in the excitation function of 7Li(7Li,4He)10Be(3.37 MeV,2+) reaction could correspond to excited states in 14C, at excitation energies around 30 MeV.
