Numerical solution of the time-dependent Schroedinger equation for a two-dimension model of H{sub 2} ionization by intense ultrashort (few cycles) extreme ultraviolet (XUV) laser pulses are presented to compare linear and circular polarization angular distributions for aligned molecules. Both ground (X {sup 1}SIGMA{sub g}{sup +}) and excited (A {sup 3}SIGMA{sub u}{sup +}) states ionization is calculated at equilibrium and for extended large internuclear distance configurations to study the effect of electron delocalization via molecular orbitals vs electron localization in Heitler-London atomic wave functions. It is found that at large distance for ionized electron wavelengths less than the internuclear distance, circular polarization ionization angular distributions exhibit signature of the entanglement of electrons by exchange, thus, allowing for a measure of exchange entanglement.
