Photoionization process is investigated for the ground state and n ≤ 3 excited states of hydrogenlike ions embedded in Debye plasmas for the entire energy range in the nonrelativistie regime.The plasm
The positron-impact excitation of hydrogen atoms embedded in plasma environments is investigated using the close-coupling approximation in the low to intermediate-energy region, and the excitation cro
The energies, free structures and Auger channel energies of triply excited resonances of Li-like ions are calculated with the saddle-point variational method.Relativistic corrections and mass polariza
在原子能院串列加速器上,利用束箔方法,测量了能量为30MeVFe离子产生的高剥离态谱线跃迁结构的寿命值.在30MeV时,Fe通过箔膜的电荷态分布在7+到17+,我们选择Fe XVI 2p6(1s) 4p-2p6(1S) 5d (2P03/2-2D3/2)的谱线,谱线波长124.696 (A),能级寿命为79±4ps.并对实验误差进行了分析.
本实验测量了20-50MeV的C离子和Au原子碰撞中Au产生的L壳层X射线,研究了Au的L各支壳层产生截面的比值σ(L1) /σ(Lα)、σ(Lβ)/σ(Lα)、σ(Lγ)/σ(Lα)和总截面的比值σ (Ltotal)/σ(Lα)并将其绘制成与入射离子能量的关系图。利用L壳层的辐射跃迁几率,Croster-Kroning跃迁率和L亚壳层的荧光产额将平面波波恩近似(PWBA)和ECSSR理论计算的电
We have measured satellite line for n=2-1 dielectronic recombination(DR) on He-like Argon.The Experiment was carried out on Shanghai EBIT and the x-ray emission spectra due to KLL, KLM, KLN, KLO, KMM,
