Abstract

Part I: The ^(14)N + ^(10)B fusion reactions have been studied at c.m. energies between 2.9 and 7.5 MeV by measuring the γ-ray yields from the residual nuclei with a Ge(Li) detector. Cross sections were deduced from these yields with the aid of statistical model calculations. ^(14)N + ^(10)B elastic scattering differential cross sections were measured from E_(cm) = 3.3 to 9.1 MeV at θ_(cm) = 74.4° and 90.0°. The fusion cross sections of ^(14)N + ^(10)B are compared with an IWBC calculation employing a parameter set obtained by fitting the elastic scattering data. Part II: Total fusion cross sections have been measured for the ^(16)0 + ^(16)0 reactions from E_(cm) = 7 to 12 MeV. Prompt γ-ray yields, measured by a Ge(Li) detector, were used to determine the cross sections for the formation of the various possible evaporation residues, as well as the total fusion cross sections, with the assistance of statistical model calculations. The total fusion cross section S-factors agrees well with previous data from this laboratory, measured by detecting evaporated light particles, and disagrees with more recent work carried out elsewhere.
