• Lifetime measurement of excited atomic and ionic states of some noble gases using the high-frequency deflection technique

High-frequency deflection (HFD) technique with a delayed coincidence single photon counting arrangement is an efficient technique for radiative lifetime measurement. An apparatus for measurement of the radiative lifetime of atoms and molecules has been developed in our laboratory and measurements have been performed with great success in a large number of atoms and ions. The present version of the apparatus is described in this paper together with a brief description of the basic features and performance

• Lifetime measurement of some excited states belonging to the 3p4nd ($n = 4–6$) conﬁgurationof ArII

The radiative lifetimes of eight levels belonging to the 3p4nd ($n = 4–6$) conﬁguration of ArII have been measured using high frequency deﬂection technique together with a delayed coincidence single photon counting arrangement. Lifetimes of some of the levels have been measured for the ﬁrst time. The results have been compared with other experimental and theoretical values.
