[Pw_forum] ion_radius

[Riping WANG]

Dear Forum,

I am using espresso-4.2.1.
In example18, for cp.x practice. I found the  " ion_radius(1) and
ion_radius(2) " in the input file.
Could you please tell me something about this input parameter, and how to
set?

as following:
 &ions
    ion_dynamics='verlet' ,
    ion_temperature='nose' ,
    tempw = .2 ,
    fnosep = 250 ,
    ion_radius(1) = 1.0 ,
    ion_radius(2) = 1.0 ,

I can not find any explanation about ion_radius from espresso manual.

Thanks very much.
