Hydrogen atom, charge cloud model

This problem illustrates the application of the charge cloud model to the hydrogen atom. 

Adopting for the C60 a fractional abundance of 4 x 10" (15% of the total elemental carbon in gas phase), Millar s model for a dark interstellar cloud at 10 K gives an appreciable abundance of protonated ion, C60 H+, and the double charged cation, C++ and also that the fractional abundance of C60 H+ is larger than C60+. Petrie et al. (1993) reported the tendency of fullerene ions (e.g. C60+ and C60++) to add atomic hydrogen repeatedly in the gas phase at 294 K. The repeated addition of hydrogen to neutral C60 in the gas phase at high temperatures (673 K) and pressures (65 atm) has also been reported by Attalla et al. (1993).
