| dc.description | The probabilities and cross sections for the 1s<sup>2</sup> <sup>1</sup>S → 2s<sup>2</sup> <sup>1</sup>S and 1s<sup>2</sup> <sup>1</sup>S → 2s2p <sup>1</sup>P transitions induced in collisions of fast charged projectiles with helium atoms have been investigated in the framework of the operator approach to the few-body problem (V A Sidorovich, Physica Scripta, accepted for publication). Calculations have been performed for the case of the 2s<sup>2</sup> <sup>1</sup>S excitation of helium by projectiles with Z<sub>p</sub> varying from 3 to 9 at collision energy E<sub>p</sub> = 1.5 MeV/u. The calculated cross sections are in satisfactory agreement with the available experimental data. The cross section dependence upon the projectile charge is established. The wavefunctions for few-electron atom, satisfying the boundary condition U = 0 (U is the interconfiguration interaction potential) in the past or in the future, and the closure relation for joint system functions are presented. |
