This energy difference, calculated by SAMUEL et al., is only approximately correct as only non-rigorous methods for the calculations have been employed. No experimental data are available in this regard. On the other hand, from our model we expect a slightly smaller value. A more accurate computatio
## Abstract Using a powerβlaw model, the two bestβknown topics in citation analysis, namely the impact factor and the Hirsch index, are unified into one relation (not a function). The validity of our model is, at least in a qualitative way, confirmed by real data.
The relationship between the resonance integral (p) and the derivative of the overlap ktegral (s) is explored for an electron trapped in two equivalent centres separated by a distance R, tie interaction at each centre being assumed to be a superposition of screened and unscreened Coulomb potentials.
