Abstract
The first AMS measurements of Ar-39 and Kr-81 have been performed by c ombining positive-ion production in an ECR ion source with acceleratio n to 6 MeV/A in the ATLAS linear accelerator and detection in a gas-fi lled spectrograph. Sensitivities of Ar-39/Ar = 8 x 10(-16) (natural ar gon), and Kr-18/Kr = 2 x 10(-10) (neutron-activated krypton)were achie ved. A full-stripping experiment for Kr-81-Br-81 separation at 45 MeV/ A was performed with the MSU K1200 cyclotron. Substantial contribution s from nuclear reactions in a Be stripper foil were observed, in the a ttempt to detect Kr-81(36+) ions in the A1200 recoil separator. The ge neral situation for the detection of noble gas radionuclides is discus sed.
