Study of cluster emission in Ra Isotopes using modified universal decay law

Cluster radioactivity was first predicted by Sandulescu et al. in 1980; these clusters were heavier than α particles and lighter than fission fragments. However, the experimental proof of this decay was given by Rose and Jones in 1984 - ¹⁴C emitted from ²²³Ra. Till now, many clusters decay from light to heavy clusters (¹⁴C to ³²Si) have been observed from various trans-lead nuclei (Fr, Ra, etc.) resulting the corresponding daughter as magic (Z=82) or neighboring nuclei which indicate the importance of this particular (Z>82) region in cluster radioactivity. In the present work, we have attempted to find various clusters which have the chances of emission from Ra (Z=86) isotopes (126≤N≤147) considering the proton shell closure effect. Therefore, we have calculated cluster decay half-lives for various clusters (isotopes of C: Z=6) from Ra isotopes by using MUDL formula given above
