Abstract:
An experiment has been designed for undergraduate educational use. Deuterons from a 150-keV Cockcroft-Walton accelerator bombarded a thin Li6 target, producing Li(d,p1)76Li*, Li(d,p0)76Li, Li(d,α)46He, Li(d,n1)76Be*, and Li(d,n0)76Be. Equipment utilized is of the type which is either in or available to many departments of modest size. Properly used, such equipment constitutes an educational tool, teaching current research methods at reasonable cost. To this end, protons, alphas, neutrons, and gammas from the above reactions have been examined in a manner designed to be most instructive. Alpha and proton energies have been measured as a function of laboratory angle, and compared with kinematic calculations. Absolute differential cross sections have been derived from these data. A spectrum has also been made of the gammas from Li(d,n1)76Be* and Li(d,p1)76Li*. Gamma-proton and gamma-neutron coincidences measurements have been used to verify energy-level assignments. Angular correlation of the observed alphas has also been studied to show conservation of momentum and the effects of center-of-mass motion.
