Dear Limin,

the input reference is there just for these kind of things.
you have two possibilities:

1) use the GENPOT (please see the few regtests available how to use it)
2) spend few more minutes of your time and instead of just looking at  
the title of the sections be curious enough
      and look into the details of the potentials available. Maybe  
named in a different way there's one  that matches your request

Please have a look at:

It is: [angstrom*kcalmol]
