ABSTRACT
We examine strong field atomic physics in a wavelength region (3-4 microns) where very little work has previously been done. The soft photon energy allows the exploration of one-electron atoms with low binding energies (alkali metals). We find that photoionization spectra differ from rare gas studies at shorter wavelengths due to more complex ion core potentials. Harmonic generation is studied, and we find that harmonic bandwidths are consistent with theory and the possibility of compression to pulse widths much shorter than that of the driving pulse. Harmonic yields in the visible and UV are sufficient for a complete study of their amplitude and phase characteristics. © 2000 American Institute of Physics.

    Abstract  For clinical purposes, the non-ceruloplasmin copper fraction is routinely derived on the basis that ceruloplasmin binds six Cu atoms. However, this approach is limited because the actual ceruloplasmin copper binding is unclear. We performed direct measurement of the total serum...

    The binding energy of the ring form of (H[SUB2]O)[SUB6] is calculated by means of the MP2 and localized-orbital MP2 (LMP2) methods. The LMP2 method is found to be effective at reducing basis set superposition error in the electron correlation contribution to the binding energy. The inclusion of...
