Dzugutov potential:[45,46]
V(r) = A(r-m - B)exp$\displaystyle \left(\vphantom{ \frac{c}{r-a}}\right.$$\displaystyle {\frac{{c}}{{r-a}}}$$\displaystyle \left.\vphantom{ \frac{c}{r-a}}\right)$Θ(a - r) + B exp$\displaystyle \left(\vphantom{\frac{d}{r-b}}\right.$$\displaystyle {\frac{{d}}{{r-b}}}$$\displaystyle \left.\vphantom{\frac{d}{r-b}}\right)$Θ(b - r).  

Seven parameters must by specified by a PARAMS line in the odata file, i.e. m, A, c, a, B, d, and b.
