You are right. This is an approximate treatment of magnetism +
spin-orbit coupling and in principle spins could mix, ....
However, for core states this is a good approximation (there is an old
paper by Guo, ... Blaha showing this for bcc Fe).

Dear WIEN2k authors and users,
Plz refer to case.inst file of Zn in pg. 84 of UG 12.1 version. In line
3 first column gives the principal quantum no., second column gives the
relativistic quantum no. which refers to a particular set of of orbital
quantum no. and spin quantum no. For example relativistic quantum no. -3
refers to l=2 & s=+1(spin up). Then why there are two lines again for
relativistic quantum no. -3 one up & one down. Please explain.
Thanks you in advance,
Saurabh Samanta
