The scattering of elementary particles by complex nuclei -— A generalization of the impulse approximation
作者： Geoffrey F. Chew , M. L. Goldberger
关键词:
摘要: By a systematic iteration procedure it is shown how the problem of scattering an elementary particle by complex nucleus (or any many-particle target system) can be expressed in terms two-body operators. The results are related to previous work Chew and Wick on impulse approximation, with special attention given multiple effects which have heretofore not been formulated rigorous way. An explicit formula for double presented.
