I set up the rigid sphere reduced collision integral, W(1,1)*
I set up the rigid sphere reduced collision integral, W(1,1)*. I attempted to set up the reduced collision integral based on the Lennard-Jones potential, but I need more help to do the numeric integration. To that end, I requested "The transport properties of non-polar gases" by J. O. Hirschfelder, R. B. Bird, and E. L. Spotz. from the Journal of Chemical Physics volume 16 p968-81 via Interlibrary Loan (ILL). In particular, I have trouble setting the reduced radius of minimum effective intermolecular & centrifugal reduced potential when it is a function of reduced collision velocty, reduced impact parameter, and reduced radius.
