## Abstract An __ab initio__ method for calculating the energies of excessβelectron bands in a molecular crystal is developed. These energies represent the electron affinities of a crystal. The present method employs a tightβbinding approximation to describe the molecules in a crystal and a set of
The bulk modulus of C60, Young's modulus of carbon nanotube, and the corresponding bond length are calculated by the tight binding method (M.J. Mehl and D.A. Papaconstantopoulos, Phys. Rev. B 54 (1996) 4519). The calculated bond lengths of C60 and the nanotube are in good agreement with experiments
