5.13 Spin Tensor Functions

5.13.1 Tcomp

Usage:


#include <IntG.h>
matrix IntG::Tcomp(int comp)

Description:

The function Tcomp is used to obtain a G interaction spin tensor component. The component desired is specified by the argument comp which relates to the m value as follows:

comp: 0 1 2 3 4

:

The spin components are given

and will be returned as matrices of dimension 2I+1 where I is the spin quantum number associated with the interaction.

Return Value:

A matrix.

Example:


IntG G(1.5, 3.e5, 0.2, 45.0, 45.0); // Make a G interaction.
matrix T20 = G.Tcomp(0); // This is the T20 spin tensor component
cout << T20); // Have a look on screen.
