Abstract  

The cross-sections for production of alpha-activities via spallation in the interaction of thorium with 600 MeV protons from the CERN Synchrocyclotron (ISOLDE beam) have been measured, employing on-line techniques. Products with half-lives in the range 4 sec<T<1 month were determined. During the course of this investigation the existence of a 62 sec isomer of222Ac was confirmed.
