What is a relation between relaxation time and mean free path for ideal gas?

These two values should be interconnected throufg integral of collisions. But I can not find a clear formula.

I dare to suggest the following article, in case that you have not yet read it.

The relation between relaxation time, mean free path, collision time and drift velocity-pitfalls and a proposal for an approach illustrating the essentials Bernhard Jakoby EUROPEAN JOURNAL OF PHYSICS; 30, 1; 1-12 (2009).
