Identical particle states and operators and the case of two-electron scattering
W. R. Ferrell, R. H. Ritchie, Trinidad L. Ferrell
Abstract
A simplified notation is introduced for dealing with systems of indistinguishable fermions and bosons. The second-quantized form of system operators is obtained in a simpler manner than is offered ordinarily in textbooks. Details of the calculation of the nonrelativistic M≂ller cross section for scattering of two electrons are given as an example.
