Photodetachment of HF^- in an Electric Field
《Chinese Physics Letters》2008年第3期919-922,共4页王德华 
Supported by the National Natural Science Foundation of China under Grant No 10604045.
Photdetachment of a negative HF^- ion in an electric field is studied by using the two-centre model and the closed orbit theory. An analytic formula is presented for the electron flux of HF^- in the presence of an ele...

Photodetachment of H- near Elastic Surface in Parallel Electric and Magnetic Fields被引量:1
《Chinese Physics Letters》2007年第7期1886-1889,共4页王德华 
Supported by the National Natural Science Foundation of China under Grant No 10604045, and the Doctoral Scientific Research Startup Foundation of Ludong University under Grant No 202-23000301.
The photodetachment cross section of H^- in parallel electric and magnetic fields near an elastic surface is derived and calculated by using the closed orbit theory. It is found that the elastic surface can produce so...

Recurrence Spectra of the Rydberg Hydrogen Atom near Two Parallel Metal Surfaces被引量:1
《Chinese Physics Letters》2006年第10期2745-2748,共4页王德华 
Supported by the National Natural Science Foundation of China under Grant No 10374061, and the Doctoral Scientific Research Startup Foundation of Ludong University under Grant No 202-23000301.
Using closed orbit theory, we study the influence of the two parallel metal surfaces on the recurrence spectra of a hydrogen atom placed in the region between the two surfaces. The results show that the metal surfaces...

Compact Arrayed-Waveguide Grating on Silicon-on-Insulator with Integrated Waveguide Turning Mirrors
《Chinese Physics Letters》2005年第12期3100-3103,共4页李广波 龚昭 贾科淼 龙文华 杨建义 江晓清 王跃林 王明华 
Sponsored by the National Natural Science Foundation of China under Grant Nos 60377030 and 60436020, the Scientific Research Foundation for the Returned 0verseas Chinese Scholars, the Shanghai Applied Material R&D Fund under Grant No 0417, and the Key Project of the Ministry of Education of China.
A compact arrayed-waveguide grating (AWG) on the silicon-on-insulator material is designed and fabricated with employment of waveguide-integrated turning mirrors (WITMs). By properly setting the incident angle wit...

Photodetachment of H^- in a Static Electric Field near a Surface
《Chinese Physics Letters》2005年第9期2233-2236,共4页杨光参 刘勇 池贤兴 
Supported partially by the Natural Science Foundation of Zhejiang Province under Grant No 102069.
The photodetachment of H^- in a static electric field near a surface is investigated based on the closed orbit theory. It is found the distance between the ion and the surface modulates the cross section of photodetac...
