Unformatted text preview: need to have a sum that adds up all of the Gibbs factors. This sum is called the Gibbs sum and is given by: Z G ( , ) = e (N -)/ Note that in taking the sum we begin with N = 0 , which has its own corresponding energies , and sum over all the states with N = 0 . Then we move to N = 1 , and so on. We can calculate the absolute probability of occupation of a state now using the Gibbs factor and the Gibbs sum just as we did with the Boltzmann factor and sum earlier....
