[lammps-users] Using Morse potential with LAMMPS

Dear LAMMPS users
I am trying to use Morse potential along with long range coulombic term Z1Z2/r^2 and the short range repulsive term Cij/r^12 term. I find the following command in LAMMPS-
pair_style morse/soft 4 0.9 10.0
pair_coeff * * 100.0 2.0 1.5 1.0
pair_coeff 1 1 100.0 2.0 1.5 1.0 3.0
and

pair_style morse/soft 4 0.9 10.0
pair_coeff * * 100.0 2.0 1.5 1.0
pair_coeff 1 1 100.0 2.0 1.5 1.0 3.0

In these cases, can someone suggest to me how to implement long range coulombic term Z1Z2/r^2 and the  short range repulsive term  Cij/r^12 term. 

Thanks
