  • In this chapter we consider a relativistic spinless particle of rest mass r¿ interacting with a fixed target. The material presented in this chapter is a review and extension of QLB: Some Lorentz Inyariant Systems Chapter 2 wherc the quantum mechanics of a fiee relativistic spinless paricle is discussed in detail. The machinery of quantum mechanics is set up and properties of the interaction potenûal between the particle and target are discussed in Section 2.2; coordinate/momentum and angular momentum bases for the Hilbert space are dìsoussed in Sections 2.3 and 2.4 and Green's operators are defined and discussed ìn Section 2.5
