Unformatted text preview: 2 and eigenvectors = 1 ) ( 1 u , = 1 ) ( 2 u , = 1 ) ( 3 u , = 1 ) ( 4 u . The electron charge e is regarded as the particle. Therefore the first two solutions (with E > 0) describe the two spin states of the electron and the last two solutions (with E < 0) describe the two spin states of the positron ( i.e. antiparticle with charge +e)....
