ISOTOPE IDENTIFICATION IN THE TRANSFERMIUM REGION BY α-α CORRELATION AFTER IN-FLIGHT-SEPARATION

Abstract

Experimental results on the production of the elements Fm to 107 in heavy ion fusion reactions of 40Ar, 50Ti, or 54Cr with isotopes of Pb or Bi are presented. The fusion products were separated from the projectile beam in-flight with their full energy as they recoil from the target. For identification they were implanted into an array of position sensitive surface barrier detectors, where α-decay or spontaneous fission were measured.
