Two particle states and the S-matrix elements in multi-channel scattering

  • 1. School of Physics, Peking University, Beijing, 100871 (China)

Description

Using a quantum mechanical model, the exact energy eigenstates for two-particle two-channel scattering are studied in a cubic box with periodic boundary conditions in all three directions. A relation between the exact energy eigenvalue in the box and the two-channel S-matrix elements in the continuum is obtained. This result can be viewed as a generalization of the well-known Luescher's formula which establishes a similar relation in elastic scattering
