Production of short lived radioactive beams of radium

Abstract

Short lived Ra212,213,214 isotopes have been produced at the TRIμP facility in inverse kinematics via the fusion–evaporation reaction Pb206+C12 at 8MeV/u. Isotopes are separated from other reaction products online using the TRIμP magnetic separator. The energetic radium (Ra) isotopes at the exit of the separator were converted into low-energy ions with a thermal ionizer. Ra isotopes have been identified by observing their α decay and half-lifes. An improved half-life of Ra213 has been measured to be 162.0±1.7s.
