Revealing the two-electron cusp in the ground states of He and H_{2} via quasifree double photoionization

Revealing the two-electron cusp in the ground states of He and H_{2} via quasifree double photoionization

We report on kinematically complete measurements and ab initio nonperturbative calculations of double ionization of He and H_{2} by a single 800 eV circularly polarized photon. We confirm the quasifree mechanism of photoionization for H_{2} and show how it originates from the two-electron cusp in th...
