In this paper, we are interested to study the distinguishing features of the decaying radioactive compound nuclei ~(246)Bk* and ~(220)Th*, using the Dynamical Cluster-decay Model (DCM) with deformation β and non-coplanar degree-of-freedom Φ. ~(246B)k* and ~(220)Th* have so-far been studied within the DCM, using quadrupole deformations (β_(2i)), “optimum” orientations (θopt) of the two nuclei lying in the same plane (Φ=0o), which shows that there is a non-compound nucleus (nCN) content in the observed data. The first turning point R_(a) (equivalently, the neck-length a??R in R_(a)=R_(1)+R_(2)+a??R), which fixes both the preformation and penetration paths, is used to best fit the measured evaporation residue (ER) and fusion-fission (ff) cross sections, σER, σff, respectively, in 220Th* and 246Bk*, formed via different entrance channels. In this work, we subsequently add higher multipole deformations, the octupole and hexadecupole (β_(3i), β_(4i)), `compact’ orientations θci and Φ≠0~(0), and look for their effects on the nCN contribution predicted by the DCM calculations referenced above.
