dear users
I want to calculate the elelectron-phonon coupling, but I found the
lambda is always larger then int alpha2F, but if I increase the
degauss larger than 1, then the lambda can equal the int alpha2F, but
the degauss should be little than 1, so I fell puzzle, is there
something wrong with me ?
-- # degauss lambda int alpha2F <log w> N(Ef)
