Abstract : Nonlinear Spectroscopy: The approach has been to study molecular systems which exhibit unusual spectroscopic behavior, in the hope that they may lead to novel techniques for upconverting laser frequencies. Also studied are novel methods of laser spectroscopy and wavelength stabilization. Tunable Laser and Coherent Light Techniques for High Resolution Ultraviolet Spectroscopy-10 papers produced. The overall theme of this contract has been on studies of the physics and technology of extreme ultraviolet (XUV) and soft x-ray lasers and devices. Much of the work has centered on methods for the production of core-excited metastable atoms and ions; and on the use of these atoms and ions both for new types of spectroscopy and for new types of XUV Lasers. An extensive study is made of the scattering of N2 off the flat, close-packed Ag(111) surface. Not only is the rotational population of the scattered N2, but also the alignment as described by the quadrople and hexadecapole moments of the J distribution, denoted by A(2) and sub 0 and A(4) sub 0 respectively.
