摘要：

The possibilities of coincident elastic recoil detection for mass analysis around mass 64 have been investigated at the GSI heavy-ion microprobe. Partial separation between the stable isotopes 63Cu and 63Cu has been obtained using a pair of position-sensitive detectors accepting both scattered projectiles and recoils between 38° and 52°. Total energy spectra gated by the peaks in the mass spectrum show small differences. For the surface nearest to the detectors depth resolution is better than 25 nm. © 1990.
