Multipoles
The multipoles can be given in 4 unique sets of isospin or charge channels  (click here for a larger image):

Further details can be found in D. Drechsel and L. Tiator, J. Phys. G 18 (1992) 449-497. (scanned version)

Type of the multipoles: (p(1/2), n(1/2), 3/2) (1/2, 0, 3/2) (0, +, - ) charge channels

Choose pion angular momentum l : El+ El- Ml+ Ml- Ll+ Ll- Sl+ Sl-

Reduced multipoles:
