Precarious Lunch
A uniform steel beam of length and mass is bolted to the side of a building. The beam is
supported by a steel cable attached to the end of the beam at an angle , as shown. The wall exerts an unknown force, , on the beam. A workman of mass
Chapter 11 Elementary Scattering Theory
As seen in the previous chapter, the bound state problem is characterized through the stationary, normalizable states in the Hilbert space. Since quantum mechanical states in principle always have to be normalized (

Chapter 12 Elements of Formal Scattering Theory
12.1 Scattering States
In the previous chapter, we more or less phenomenologically derived the boundary conditions for the scattering states. We now want to introduce a more formal de nition. The time-depend
Chapter 1 Quantum Mechanics in Hilbert Spaces
1.1 The Abstract Hilbert Space
The essential results in quantum mechanics are given through purely algebraic relations. Speci c results can be derived, e.g., for vectors 2 `2 and matrices being linear maps; ho
