Extended Stevens operators.
Syntax
S=stevens(mult,k,q)
Parameters
mult - multiplicity of the spin in question
k - Stevens operator rank, a non-negative
integer
q - Stevens operator projection, an
integer between -k and k
Outputs
S - Stevens operator matrix
Notes
For historical reasons, the definition of Stevens operators is irregular and must rely on explicitly stockpiled coefficients. Only ranks smaller or equal to 12 are available.
