摘要：
The use of optical methods for the detection of plasma waves requires the consideration of propagation properties of waves as well as the excited state lifetimes. In case of known propagation properties of waves the excited state lifetime can be determined from the frequency-dependent decrease of the wave amplitude. The proposed technique represents a new independent method for the determination of excited state lifetimes. This paper deals with first studies on excited state lifetime based on the frequency response of the amplitude of free streaming electron waves in He-dc-discharges. The results demonstrate the correctness of the idea about the decrease of wave signal in consequence of excited state lifetime.
