    "abstract": "A decomposition of the angular momentum of the classical electromagnetic\nfield into orbital and spin components that is manifestly gauge invariant and\ngeneral has been obtained. This is done by decomposing the electric field into\nits longitudinal and transverse parts by means of the Helmholtz theorem. The\norbital and spin components of the angular momentum of any specified\nelectromagnetic field can be found from this prescription.",
