[Ifeffit] phase problem copper

Dear all,
I have a standard exafs  spectrum of copper K-shell and everything  looks as expected (Chi(E), Chi(k), Chi(R), Chi(q) …) when using Demeter 0.9.21 .
However the phase spectrum of (Chi(q))  appears quite different to literature (e.g. B.K. Teo, Inorganic Chemistry Concepts 9; Martens et al, PRB 17, p1481 (1979),  i.e. positive slope, a factor of ~10 larger values on y-axis.
Any reason why? Thanks for your answer in advance.
Regards, Matthias
