利用同步辐射高等光源激发氮原子测量了在能量范围63-66eV的双电子激发态的真空紫外辐射光谱,给定了sp,2n(n至26),sp,2n-(n至24)和2pnd(n至9)的氮原子双电子激发态能级位置,获得了一些对认识原子双电子激发态过程中辐射跃迁的影响有价值的结果.
Helium doubly excited states and their radiative spectra in VUV region of 63-66 eV were investigated by means of advanced synchrotron radiation source. The energies of the doubly excited states sp, 2 n + ( n up to 26), sp ,2n - ( n up to 24) and 2pnd( n up to 9) were determined and some valuable results on the role of radiative transition in dynamics of atomic doubly excited states were also discussed.
