Paper Abstract

We studied the UV and x-ray double-resonance absorption process in the case of 1 micrometers tryptohan. By adopting a three-state model for ultra-violet (UV) absorption we could calculate the excited molecular density. We also calculated the x-ray transmittance dependence on the UV-laser photon flux using x-ray absorption cross section obtained by a calculation based on the atomic Hartree-Slater method. We found that strong x-ray absorption occurs in the UV region with a photon flux of approximately 1025 photons/cm2/sec. Furthermore, we considered the feasibility of x-ray microscopy using double-resonance absorption. It is expected that only the images of selected molecules can be obtained with a good S/N.
