Why this formula appears here
where has units of inverse seconds, interaction time has seconds, and = is dimensionless. The factor 2j is a declared normalization choice, not an inherited law. Alternative normalizations must be compared because they change the large- j limit if coupling strength is held fixed under different conventions.
