Greetings to all,

I am working on a diffraction problem and I am having some troubles
with the function exp(-i*x)*erfc(sqrt(-i*x)). I think it is related
to the plasma dispersion function and I am interested in finding the
behaviour of the function as function of x. I have found that it is
decreasing in amplitude for increasing values of x but I must find
how to show it. All I could find is a tabulation in Abramowitz-Stegun.

Any hind is welcome and very appreciated. Please reply to my e-mail.

Thanks in advance.
