    "abstract": "Excited state angular momentum alignment -- orientation conversion for atoms\nwith hyperfine structure in presence of an external magnetic field is\ninvestigated. Transversal orientation in these conditions is reported for the\nfirst time. This phenomenon occurs under Paschen Back conditions at\nintermediate magnetic field strength. Weak radiation from a linearly polarized\ndiode laser is used to excite Rb atoms in a cell. The laser beam is polarized\nat an angle of pi/4 with respect to the external magnetic field direction.\nGround state hyperfine levels of the 5S_1/2 state are resolved using\nlaser-induced fluorescence spectroscopy under conditions for which all excited\n5P_3/2 state hyperfine components are excited simultaneously. Circularly\npolarized fluorescence is observed to be emitted in the direction perpendicular\nto both to the direction of the magnetic field B and direction of the light\npolarization E. The obtained circularity is shown to be in quantitative\nagreement with theoretical predictions.",
