【摘要】 <正> 碳离子是高温等离子体中主要的杂质之一,在用光学方法测定高温等离子体中杂质浓度和分布时能级寿命参数带来很大的不确定性和误差。我们将用束箔光谱方法对高温等离子体有关杂质光谱能级寿命和跃迁几率进行研究,这里只给出碳的束箔光谱研究的初步结果。更多还原

【Abstract】 When a monoenergetic (175keV, 1μA) beam of 12C+ ions passed through a 5-10μg/cm2 carbon foil, a beam-foil spectroscopic source of atomic and ionic carbon was produced in various stages of ionization and electr onic excitation. Spectra, radiative lifetimes and transition probabilities had been obtained by the beam-foil method for many excited terms in CⅡ-CⅢ.更多还原
