Abstract:Universality of the dynamic characteristic relationship between the characteristic time t c and the two-electron Coulomb interaction energy V 12 of the ground state in the two-photon double ionization process is investigated through changing the parameters of the two-electron atomic system and the corresponding laser conditions.The numerical results show that the product t c V 12 keeps constant around 4.1 in the cases of changing the nucleus charge, the electron charge, the electron mass, and changing simultan… Show more
