When an unknown object with Lambertian reflectance is viewed orthographically, there is an implicit ambiguity in determining its 3-d structure: we show that the object‘s visible surface f(x, y) is indistinguishable from a “generalized bas-relief” transformation of the object‘s geometry, \bar f (x, y) e λf(x, y) + μx + νy, and a corresponding ...

Giant Resonances in the 4d Subshell Photoabsorption Spectra of Ba, Ba+, and Ba++
1987Evidence of giant resonances in the ionized series Ba, Ba+, Ba++ has been shown in the calculations of the photoabsorption spectra near the 4d ionization threshold by employing the time-dependent local density approximation (TDLDA). It is shown that for positive excitation frequencies, TOLDA is essentially equivalent to the conventional random phase ...
