【摘要】 本文叙述了一种新型的低气压对称放电热管炉,用它研究了铕原子不同气压下的双共振光电流光谱,新观察到铕元素由17341cm^-1能级出发的4条新谱线,由16612cm^-1能级出发的3条新谱线.实验证明这种热管炉比较适合于研究高Z金属元素的高激发态光谱.更多还原

【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.更多还原
