Theoretic Study of CIIRecombination Line

Autor: LI Jia-Ming, Wang Min-Sheng, Han Xiao-Ying, Peng Yong-Lun

Publikováno v: Chinese Physics Letters. 21:1723-1726

Using the R-matrix method, we carry out theoretical calculations for recombination line λ 8794 A(3d'-3p') of CII, which is important to estimate the abundances of carbon in planetary nebulae. Our calculations are based on three sets of target orbita

Relativistic Multichannel Theory: Theoretical Study of C + Autoionization States

Autor: Xia Dan, Zhang Shi-Zhong, LI Jia-Ming, Peng Yong-Lun

Publikováno v: Chinese Physics Letters. 20:56-59

Based on relativistic multichannel theory, the autoionization states of C+ are studied. We calculate all the autoionization states in the energy region of 193900similar to231700 cm(-1), and the results are in good agreement with the experimental data

Relativistic Multichannel Treatment of Krypton Spectra across the First Ionization Threshold

Autor: QU Yi-Zhi, Peng Yong-Lun

Publikováno v: Chinese Physics Letters. 22:1884-1886

The relativistic multichannel theory has been extended to calculate both the eigen quantum defects ??, transformation matrix Ui?, and the eigen dipole matrix elements D? of krypton. The Rydberg and autoionization spectra of krypton across the first i

Theoretical Analysis of Ionic Autoionization Spectra of Lanthanum in the Energy Region of 90650-91500 cm -1

Autor: Zhong Zhi-Ping, Peng Yong-Lun, Xia Dan, Zhang Xin-Feng, Xue Ping, QU Yi-Zhi, Xu Xiang-Yuan, Sun Wei

Publikováno v: Chinese Physics Letters. 20:1242-1243

Eigenquantum defects µα and transformation matrix Uiα of La+ are calculated from the first principles by relativistic multichannel theory, and dipole matrix elements Dα are obtained by fitting the experimental spectra. With these parameters, ioni
