摘要：

A neutralized ion beam photoionization technique has been used in an attempt to detect the lowest triplet state in ammonia. Although triplet ammonia molecules are a likely product of the neutralization reaction, only highly excited Rydberg states were observed by photoionization. The absence of the triplet state is most likely due to its rapid predissociation rate.
