Calculation of photon angular distribution and polarization for radiative recombination for high-charged hydrogen-like ions

In this paper a systematic study is carried out on the angular distribution and polarization of photons emitted following radiative recombination of H-like ions by a non-relativistic dipole approximation. In order to incorporate the screening effect due to inner-shell electrons, a distorted wave approach is used. The dependences of the calculated angular distribution and polarization on the reduced energy and nuclear charge are fitted by the corresponding empirical formulas respectively.     

非视域快速成像系统研究初探

非视域(Non-Line-of-Sight, NLOS)成像技术可以对被其他物体遮挡住(如拐角处、烟雾后等)的隐藏目标进行探测和成像,因此在机器视觉、安防、医学影像、灾难救援和自动驾驶等领域具有重要的应用价值。该技术通过利用脉冲激光束和时域信号探测器扫描特定表面来实现上述功能。目前NLOS技术仍然存在诸多不足之处,比如扫描时间长、计算时间长等。针对这些情况,提出了一种凝视型快速探测与重建方法。模拟结果表明,该方法可探测高反射物体,并可有效增大视域范围。

Resonance Excitation Rate Coefficient of Ni-Like Tantalum

The ab initio calculations of electron-impact resonant excitation rate coefficients from the ground level to 54 fine-structure levels of 3d94l （1 = s, p, d, f） configurations of Ni-like tantalum ion are performed by using a fully relativistic distorted-wave approximation. The configuration-interaction effects are taken into account. The decays to autoionizing levels possibly followed by autoionization cascades are also included in the calculation. The contributions from doubly-excited intermediate states of Cu-like 31^17n′l′n′l″ （n′ = 4, 5; n″ = 5 - 15） are calculated explicitly, and the contributions from high Rydberg states （n″〉 15） are taken into account by using n-3 scaling law. The present results should be more accurate than the existent calculations.

Photon Angular Distribution and Polarization of Radiative Recombination

A systematic study is carried out on the angular distribution and polarization of photons emitted following radiative-recombination of bare and He-like ions of Ne, At, Ni and Mo with a unidirectional electron beam. In order to incorporate the screening effect due to inner-shell electrons, a distorted wave method is used. Scaling rules for polarization of the photon following radiative recombination to both bare and He-like ions are given for the incident energy regions up to six times the ionization threshold energy of the final state.
