Charge-exchange reactions with a radioactive triton beam

Abstract

A high-resolution (t, 3He) test experiment has been performed recently by making use of a secondary triton beam produced by fragmentation of α-particles. The purpose of this charge-exchange experiment was to achieve good energy resolution in an (n,p)-type reaction at intermediate bombarding energies. The experiment was carried out with the K1200 cyclotron at the National Superconducting Cyclotron Laboratory using the A1200 beam-analysis system and the S800 magnetic spectrometer. The beam-analysis system was used to transport the energy-dispersed radioactive triton beam from the production target to the target position, and the magnetic spectrometer was used to focus the dispersion-matched 3He particles from the (t, 3He) reaction at 0° onto the focal plane of the spectrometer. An energy resolution of 200–250 keV was achieved.
