Аннотация:
The possibility of using the correct asymptotic form of the continuum wavefunction recently proposed by Altick (1982) to calculate the double photoionisation cross section of atomic systems is investigated. The helium atom is considered as a test system. The result of the author's investigation shows that the impact of the Altick function on the cross section of He is encouraging at relatively high incident energies.
