We found that there is a scope to identify the new isotopes for Bk which has half-lives greater than 10-6s. Our theoretical calculation (see Appendix IV) predicts that the next heavy nuclei with Z=97, N=139 (A=236, T1/2=0.933s (β-decay)) can be synthesized with a good residual cross-section of 87pb by the target of 209Bi and projectile of 30Si at about 147.53 MeV.
