5. A. B. Migdal, Zh. Eksp. Teor. Fiz.,28, 3, 1955. Sov. Phys. JETP,1, 2, 1955. The idea of studying then−n interaction from the fsi in the three-nucleon break-up was given byMigdal in 1952 in a Landau seminar presented at Moscow (Institute of Physical Problems, Acad. of Sciences). Independently,K. M. Watson, Phys. Rev.,88, 1163, 1952, suggested the fsi effect in more general reactions.
