Abstract

Angular distributions of α-particles emitted in the ⁹Be(n, α₀)⁶He reactions have been measured at neutron energies of 12.2, 14.1 and 18.0 MeV. Excitation functions for forward emission of the reaction products have been determined in the neutron energy range 12.2–18.0 MeV. The results indicate the dominance of heavy particle stripping in the mechanism of the ⁹Be(n, α₀)⁶He reaction in the investigated neutron energy range.

Measurements of charged particles from fast neutron induced reactions in the close geometry
1982, Nuclear Instruments and Methods In Physics Research
A compact experimental arrangement (called the “close geometry”), which was investigated for the purpose of measuring identified charged-particles from 14.1 MeV neutron-induced reactions of relatively low cross sections, has been described and discussed. The ³Hd neutron source, a target and two counter telescopes consisting of silicon detectors and gas proportional counters were inserted in a small scattering chamber designed specially for this purpose. The apparatus followed by a data-acquisition system developed on the basis of the CAMAC standard has been employed successfully for the measurement of differential cross sections for 14.1 MeV neutron-induced reactions on light nuclei.

1979, Nuclear Physics, Section A
The ¹¹B(n, α)⁸Li reaction has been studied at 14.4 MeV in a geometry that allows simultaneous detection of the emitted and recoil particles. The angular distributions have been measured for the transitions to the ground and first excited states of the ⁸i nucleus and compared with PWBA for knock-on and heavy-particle pick-up processes. The total cross sections for the respective transitions have been deduced.
