[Pw_forum] Need Pseudo potentials

[priyanka goud]

Dear PWSCF users,

                                    I need pseudo potentials for Rb(
Rubidium)  metal.
I have gone through this website
(http://www.quantum-espresso.org/pseudo.php) for the same.
 But there are some elements(eg:Rb,Fr etc) for which pseudo potentials
has not been defined.

Is there any way to retrieve pseudo potentials for such elements(My
case is Rubidium-Rb).

Thanks in Advance.
