So I was given this link, and was happy that I have now the epsilons and sigmas that I can use in Lennard-Jones potential calculations, but found out that the information in other sources is very different.
It says here:
"The ϵ and σ values for Xenon (Xe) are found to be 1.77 kJ/mol and 4.10 angstroms, respectively."
Which is different from the table in first link which says epsilon = 0.0238880 eV (2.304881456 kJ/mol) and sigma = 2.4945200 angstroms.
I understand that there could be some insignificant differences, but these are rather big ones. Maybe I am not correctly reading the table (ignoring cutoff) or something else?
