Abstract
Показано, що двоелектронна хвильова функцiя системи “атом водню + фотоелектрон” у борнiвському наближеннi забезпечує високу точнiсть розрахунку поперечного перерiзу процесу фотоiонiзацiї негативного iона водню. Розраховано частковi
поперечнi перерiзи, що вiдповiдають рiзним “ns-каналам реакцiї” у шкалi енергiй
фотоелектрона i шкалi довжин хвиль. Виконано порiвняння з результатами iнших
авторiв, одержаних iншими методами.
It is shown that the two-electron wave function of the system “hydrogen atom + photoelectron” in the Born approximation provides high accuracy of the photoionization process cross-section calculation of negative hydrogen ion. The partial cross-sections, which correspond to different “reaction ns-channels” in the scale of photoelectron energy and the scale of wavelengths are calculated. The comparisons with the results of other authors which obtained by other methods are performed.
