Özet:

 

Rare earth nuclei are probable candidates for exhibiting cluster  radioactivity.  In the present work, a theoretical study of alpha  decay and heavy cluster emission from Dy, Er, and Yb nuclei in the  mass range 150 < A < 190 has been carried out in a fission model  approach.  Some of the proton-rich isotopes of these nuclei are found  to have long half-lives, but within the measurable range.  Many of the  neutron-rich isotopes under consideration are far from beta  stability and the most probable light clusters predicted are highly  exotic in nature and the corresponding half-lives are extremely short.  However, the decays of most probable heavy clusters predicted have  half-lives in the measurable range.  The calculations on neutron-rich  isotopes indicate the emergence of new magic numbers for protons and  neutrons.  The centrifugal barrier effect on decay rate of some  proton-rich Er isotopes is also investigated.
