A new classification scheme of angular momentum coherences based on the dynamical symmetry group 0 4 of hydrogen is proposed. The existence of a specific constant of motion, the Runge-Lenz vector, enables an extension of the Fano-Macek approach to mixed-/ coherences observed in inelastic atomic collision processes. Using a SU(2) x SU(2) pseudospin formulation a correspondence between the complete n-shell density matrix and the expectation values of multipoles of the angular momentum and the Runge-Lenz vector is established. Explicit expressions are given for n = 2 and n = 3.

Abstract. The Stark beats of Lyman-e emission due to n = i -2 transition of hydrogen atom have been studied by the beam-foil method. After passage through a thin carbon foil, the static electric field of 500 V/cm was applied to the beam in the direction either parallel to or anti-parallel to the the beam velocity. The linearly polarized emission was measured by using a toroidal mirror at a Brewster's angle reflection. When the direction of the applied electric field is reversed, an appreciable phase shift was observed. The analysis of the data leads to the complete determination of the density matrix of the H(n = 2) atoms at the time of their production.
