hi folks,
I want to calculate the potential energy part of the partition function of 2 particles interacting via the Lennard-Jones potential. This partition function should be proportional to:
[itex]\int_0^\infty exp(-\beta * 4((\frac{1}{r})^{12}-(\frac{1}{r})^6)) dr[/itex]
But this integral won't converge, since the integrand is approx. equal to 1 for large r.
What is my mistake?
