Syntax

g=geffect(spin_system,states)

Arguments

states - the numbers of the states to use

            (numbered sequentially from the 
             lowest to the highest energy)

Outputs

Version 2.2, authors: Elizaveta Suturina, Ilya Kuprov

Description

Lanthanide systems often have multiple pairs of energy levels that are related to one another by a spin flip. These are called Kramers doublets. This function returns the effective g-tensor for the user-specified pair of levels.

Returns

g - 3x3 g-tensor matrix in Bohr mag-

            neton units
