More on Asymptotic behaviors of 9j Coefficients
Abstract
Previouslywe noted in numerical calculations that a certain unitary ninej coefficient U9j =((jj)2j (jj)2j | (jj)2j (jj) (2j-2))I decreases with increasing j and for small I the decrease is of the form C jm e-α j . The exponential decay dominates. It is here shown that α = 4 ln(2) and m=3/2.
