Yeah , the e The effect I don't  @ @ I can understand the effect of this , no ? because it 's to  to do something like that.
Well , it says , since you 're taking a natural log , it says that when  when you get down to essentially zero energy , this is gonna be the natural log of one , which is zero.
No ? Mm - hmm.
So it 'll go down to uh to  the natural log being  So the lowest value for this would be zero. So y you 're restricted to being positive. And this sort of smooths it for very small energies. Uh , why they chose sixty - four and something else , that was probably just experimental. And the  the  the constant in front of it , I have no idea.
