I'm puzzled by the appearance in the literature of 2 conflicting forms:
P(E)=√(E)*exp(-E), which I understand as derived from the Maxwell distribution for speed.
It is a chi -square distribution with 3 degrees of freedom.
P(E)=exp(-E), which seems wrong to me.
But it is not simply a mistake because numerous reputable sources give each form. What is the relationship?
