The first turning point Ra (equivalently, the neck-length ∆R in R<sub>a</sub>=R<sub>1</sub>+R<sub>2</sub>+∆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, σ<sub>ER</sub>, σ<sub>ff</sub>, respectively, in <sup>220</sup>Th* and <sup>246</sup>Bk*, formed via different entrance channels. In this work, we subsequently add higher multipole deformations, the octupole and hexadecupole (β<sub>3i</sub>, β<sub>4i</sub>), `compact’ orientations θ<sub>ci</sub> and Φ≠0<sup>0</sup>, and look for their effects on the nCN contribution predicted by the DCM calculations referenced above.</p> ER -
