摘要：

We observe vibrational states by photoassociation spectroscopy of cold He(2(3)S) atoms. Photoassociation resonances are detected as peaks in the Penning ionization I rate over a frequency range of 20 GHz below the atomic 2(3)S(1)-2(3)P(2) transition frequency. We have observed three vibrational series, or which two can be identified. A possible mechanism to explain the observed increase of the Penning ionization rate is discussed.
