[Pw_forum] Regarding Van der waals corrections for Xe

[Kondaiah Samudrala]

Dear all,
I have two doubts regarding Van der waals correction methods:

There is no C6 value for Xe. Whether I can use for "london=.true." option
for Xe base compounds???

Whether london=.true. for all functionals ( i mean, LDA, PW91, PBEsol) or
explicitly for PBE only????

Thanks in advance

with regards
