Abstract

In this paper we deseribe a new low pressure symmetric discharge heat pipe (LPDP) which may be used to generate high Z low pressure metal vapour sample. Wes have studied the double resonance opto-galvanic spectrcscopy (DROGS) of Eu atom in different pressure with the LPDP. Four new lines of Eu froml7341cm-1 excited level and three from 16612 cm-1 are observed for the first time. It is verified that such a new LPDP is suitable for studying highly excited state speotroscopy of high Z metal elements.
