Many Van de Graaff accelerator-type experiments can be performed at modest and even low bombarding energies. In general, for incident particle energies below 150 keV, one is restricted to proton- or deuteron-induced reactions on light target nuclei. This restriction is, of course, due to the Coulomb barrier for most reactions in this energy interval. Several reactions which are feasible with existing equipment found in many universities throughout the United States and foreign countries are discussed. Necessary modifications to existing Cockcroft-Walton-type accelerators are outlined, and the general experimental procedures for reactions of the type12C(p,p) 12Cand11B(p,α) 8Beare given.
