# The standard PseudoDojo pseudopotentials for Mg only include l=0 and l=1
# in the non-local part, in contrast to most other Group I and II elements.
# For those elements (K, Ca and beyond) we provide an accurate PAO basis
# which includes both l=1 and l=2 polarisation orbitals, but we cannot do
# that here, so we default to l=1 (though see below for more details).

# Polarisation orbitals are potentially problematic for Groups I and II.
# The highest energy valence orbital is l=0 so the polarisation orbital
# using the standard perturbative approach would be l=1, but that would
# mean a basis set with only l=0 and l=1. It is also possible to polarise
# perturbatively from the highest energy l=1 orbital to give a polarisation
# orbital with l=2 using the lines below, but this will be perturbing a
# semi-core state and will give a basis where the only l=1 orbitals are
# semi-core states. This may not be reliable: we recommend careful testing
# should you choose this route.
