Basic Aspects of the Programs
The LEED programs assume the input to be expressed in Ångstroms for lengths, electron-volts for energies (except in the phase shift input, where energies are in hartrees), degrees for angles (radians for phase shifts) and kelvins for temperatures. Internally these programs work in atomic units (ℏ=e=m=1), i.e. in Bohr radii for lengths and hartrees (double rydbergs) for energies, and in radians for angles and kelvins for temperatures. Output quantities have mixed units: see Chap. 10.
