Hi everyone,
I am giving artemis the following parameters:
guess amp 1
def delr alpha*reff
guess enot 0
def ss debye(temp,thetad)
set alpha .0002
set thetad 343
set temp 298
But I am not getting a very good fit. The value of debye temperature is
343 for Cu( Kittel book) but I got to know that some persons even guessed
the value of thetad as 285+-16 . I am not getting that how we can guess the
value of alpha and thetad . Also I am not getting the value of Ei, 3rd and
4th cumulant in the fit results . So How can I get the value of these
parameters in the fit results .
With thanks
Abhijeet Gaur
