On the indefinite metric in the lee model
A consistent set of rules was previously developed for handling the Lee model when the coupling constant is imaginary. It is pointed out that the metric operator needed in such a formalism is not unique and that it may result in giving complex norms to states that may or may not contain the ghost state. This freedom is shown not to affect the interpretation of scattering experiments.
