Search for delayed α-decay of high spin isomers in heavy-ion induced fusion reactions

  • Published:

Abstract

A search forα-decay of high spin isomers in the mass range 140<A<200 is reported. Fusion reactions with beams of132Xe and50Ti have been used to provide high velocity recoils with angular momenta beyond 50ℏ. Recoil distance experiments sensitive to half lives longer than 10 ps and shorter than about 1 ns have been performed for 31 different compound nuclei. Within a sensitivity of 1–30μb per event no delayedα-emission has been observed.
