Abstract
The effect of beam intensity and beam pulse repetition rate on the transport efficiency of
104Ag recoils [from the
103Rh(α, 3n) reaction] in a He jet recoil transport system has been measured. Transport was effected by using the gas doped with benzene or diethyl sulphide. The effect of concentration for these two substances has been established and the maximum transport efficiencies were about 100% for benzene (22 ppm) and about 80% for diethyl sulphide (12 ppm).
