摘要：

The calculation of the radiative lifetime for weakly bound He(2(1)S)-Ne molecules in the lowest vibrational state based on recent improved quantum chemical data is performed for the first time. The obtained value of 13 ns is counterintuitively of the same order as lifetimes for allowed optical transitions. The radiative decay is determined for both the bound-bound and bound-free transitions.
