Dear Peter, As a followup --- I did a comparison study on a case of non-spin-polarized spin-orbit coupling with my procedure and the tricks in the UG. With my procedure, x lapw1 -p x lapwso -p x lapw2 -c -so -p x opticc -so -p x joint x kram The results (case.symmat, case.outputjoint,

Dear Peter and Respectful Wien Users, 1/ In the UG, page 147, I notice the following for the optical properties calculations In cases of non-spinpolarized calculations WITHOUT inversion symmetry AND spin-orbit coupling, one must do some tricks and ?mimick? a spinpolarized calculation: I
