NiSi sub 2 is an important material that has been studied both theoretically and experimentally, and it has been assumed to have a bulk-terminated (111) surface structure.

Valence band photoemission measurements have been made both above and below the T sub c of Ba sub 2 YCu sub 3 O (9-delta) where delta = 2.1.

Epitaxial CoSi sub 2 terminated with a thin Si bilayer has been studied by synchrotron radiation photoemission.

We present a comparative study of ultrafast photoexcited state relaxation in pentacene single crystals and in pure and C(60)-doped pentacene films using optical pump-probe spectroscopy.

We have observed unambiguously the coherent tunneling of photoexcited electrons through an unequal Al sub x Ga sub (1-x) As double barrier superlattice structure.

Antimony and bismuth cluster cations are produced by laser vaporization in a pulsed nozzle source and probed with mass spectroscopy and mass selected photofragmentation at 248 nm.

The reaction of 3,3'-dimethylbicyclopropenyl (1) with photoexcited electron acceptors (chloranil, fluoranil) results in conversion to a 4:1 mixture of o- and m-xylene.

Large population inversions on transitions ranging in wavelength from 109 to 78 nm have been produced in six elements pumped by photoionization via inner-shell and/or multi-electron (shakeup) proce

Large population inversions have been obtained in Cd and Zn ions using broadband soft-x-ray radiation from laser-produced plasmas to photoionize and thereby remove inner-shell d-electrons from the

We propose to construct an inner-shell photoionization laser in sodium at 37.2 nm by photoionizing sodium vapor with the 20.6 and 20.9 nm outputs from the Lawrence Livermore National Laboratory (L
