Cluster radioactivity in superheavy nuclei 299-302120

Abstract

The cluster radioactivity is an unusual decay process observed in superheavy nuclei. When a cluster nuclei are emitted, the residual or daughter nuclei is having doubly magic nuclei or it may be neighbourhood of the same. We have studied cluster radioactivity [⁴He, ⁶Li, ⁹Be, ^20,22Ne, ²³N, ^24-26Mg, ^28-30Si, ³¹P, ^32-34S, ³⁵Cl, ^36,38,40Ar, ^40-46Ca ] in the superheavy nuclei ^299-302120 using the nuclear and proximity model. The calculated cluster decay half-lives are compared with that of the other theoretical models such as Univ¹, NRDX², UDL³ and Horoi⁴. From the comparison of different models we have observed that the cluster nuclei with ⁴He, ⁹Be, ²²Ne, ²⁶Mg, ³⁰Si, ³⁴S, ⁴⁰Ca and ⁴⁶Ca are having smaller logarithmic half-lives than the exotic cluster decay modes.
