Dear Payami,

Actually, I don't have too much experience about generating pseudo
potential.
However, you may change the rcut in order to generate the desired PP.
E.g. you can run the code by choosing :
5
2S  1  0  2.00  0.00  5.0  5.0
2P  2  1  6.00  0.00  4.50  4.50
3S  3  0  2.00  0.00  4.50  4.50
3P  4  1  1.00  0.00  4.50  4.50
3D  5  2  0.00 -0.10  4.0  4.0

Although, they do not give any reliable results and still you also have to
get rid of warning in the out file:
"WARNING! Expected number of nodes:   0=     2-  1-  1, number of nodes fou
nd:  1.
       Setting wfc to zero for this iteration.
       (This warning will only be printed once per wave function)"

Of course, the professionals will give you more comments!

Yours,
