Study of the /sup 233/Th(. gamma. ,xn)226,222/supTh/ reaction at. gamma. -energies <= 60 MeV using a helium jet

Abstract

A helium jet system is set up for the transport and investigation of daughter products of the nuclear reaction /sup 232/Th (..gamma..,xn) at E/sub..gamma../<=60 MeV. The theoretical fundamentals for the target kinematics such as photoexcitation, evaporation cascade and range of heavy ions are presented. Activation experiments with thick thorium tetrafluoride targets and catcher foils for the reaction products emitted showed a nuclide-dependent forwards-backwards ratio which agrees with the calculated values within 1-2 standard deviations of the statistic error. A target system with thorium nitrate coated glass wool is tested with the helium in 'on-line' operation and after irradiation is used for the investigation of the long-lived activities with the excess pressure jet. The radioactive decay series of the transported reaction products are identified by alpha spectroscopy.
