Abstract:

Transitions from the 2p. sup. 4 (. sup. 1 S. sub. 0)3s. sup. 2 S. sub. 1/2 state of atomic fluorine to all allowed lower states produces laser emission at six new wavelengths: 680. 7. ANG. , 682. 6. ANG. , 3592. 7. ANG. , 3574. 1. ANG. , 6089. 2. ANG. , and 6046. 8. ANG. Coherent radiation at these new wavelengths can be generated in an atomic fluorine laser operated as an amplifier or as an oscillator.

Abstract:

An assembly is provided for securing a rail to a supporting tie and includes upper and lower plate members engaging corresponding tie surfaces. The upper plate member is interposed the base of the rail and the tie upper surface. A portion of the upper plate member projects outwardly from the rail base and is apertured. The aperture is aligned with a hole in the tie extending transversely between the corresponding tie surfaces. The lower plate member is provided with a slotted aperture aligned with the tie hole. A resilient clip overlies the upper plate member apertured portion and includes apertured inner and outer sections disposed in resiliently spaced relation. Apertures in the clip sections are aligned with one another and the upper plate member aperture. A lock element is provided having a head end, a distal end, and a shank interconnecting the ends. The distal end has lateral extensions.
