SE-SCM Interpretation of Fissioning Processes

The method we adopt in this section for further studying metal-cluster fission is the SE-SCM described in Section 4.2.2.6 (see also Ref. [43]). 

As discussed above (see Section 4.2.2), in the SE-SCM method we need to introduce appropriate empirical potentials. As will become apparent from our results, one-center potentials (like the one-center modified, anisotropic harmonic oscillator) are not adequate 

In addition to the present shape parameterization [43], other two-center shape param-eterizations (mainly in connection with KS-LDA jellium calculations) have been used [81-83] in studies of metal-cluster fission. They can be grouped into two categories, namely, the two-intersected-spheres jellium [81, 84], and the variable-necking-in parame-terizations [82, 83]. In the latter group. Ref. [82] accounts for various necking-in situations by using the funny-hills parameterization [85], while Ref. [83] describes the necking-in 

As a demonstration of our method, we present results for two different parents, namely Naio and Naig.  

The middle panels exhibit the decomposition of the total barrier into the three components of surface. Coulomb and shell-correction terms (see Eq. (41)), which are denoted by an upper dashed curve, a lower dashed curve and a solid line, respectively. The total
