Title: Molecular Symmetry-Mixed Dichroism in Double Photoionization of $H 2$

Abstract

Dichroism in double photoionization of $$H_2$$ molecules by elliptically polarized extreme ultraviolet pulses is formulated analytically as a sum of atomiclike dichroism (AD) and molecular symmetry-mixed dichroism (MSMD) terms. The MSMD originates from an interplay of $^1Σ$$^+\atop{u}$$ and $^1Π$$^+\atop{u}$$ continuum molecular ionization amplitudes. For detection geometries in which the AD vanishes, numerical results for the sixfold differential probabilities for opposite pulse helicities show that the MSMD is significant in the electron momentum and angular distributions and is controllable by the ellipticity.
