【摘要】 对铀原子单色和双色多光子共振电离光谱，进行了深入的研究。把亚稳态３８００ｃｍ－１做为起始态，用双色三光子共振电离技术，在３７９００～３８６５４ｃｍ－‘范围内获得了６０个铀原子奇宇称高激发态能级的能位值和Ｊ值。更多还原

【Abstract】 The singlecolour and two-colour multiphoton resonant ionization spectra of uranium atom have been studied extensively’ 60 energy locations and J assignments of high-lying odd levels in the 37900-38654 cm-1 region by two-colour three-photon resonant ionization technique were observed using the metastable level of uranium at 3800cm-as the initial level.更多还原
