Abstract

Various channels from the 14N + 159Tb reaction at 140 MeV were studied using γ-particle coincidences combined with γ-ray multiplicity measurements. A wide class of binary reactions ranging from typical incomplete fusion processes to few-nucleon capture reactions was selected and investigated. Energy spectra, absolute cross sections and average γ-ray multiplicities were measured for a large number of reaction channels. From a detailed kinematical analysis it was found that all the reactions quite precisely satisfy the “recoil formula” of Siemens et al. for hard-grazing collisions. It is attempted to describe this wealth of reaction data on the common footing of the sum-rule model that combines the idea of partial statistical equilibrium with a generalized concept of critical angular momentum. The experimental results seem to confirm the basic assumptions of the model.
