摘要：
The experimentally established systematic difference between the measured and calculated effective lifetimes of the Rydberg states of the helium atom in the presence of strong population mixing is explained by the existence of losses during collisional excitation transfer. A simple equation for calculating the effective lifetime is proposed.
