Hello,
I am trying to study a system consisting of Li,Cl and O. I am
using pseudopotentials of PAW(pbe) type for Li,Cl and O with suggest
minimum wavefunction cutoffs 78Ry, 36Ry and 47Ry respectively.
From the literatures , it is clear that everyone is using cutoff
less than 50Ry, but I found that total energy is conserved for a cutoff of
80Ry from scf calculations.
In this case, what cutoff should I use?
Thanks
