| 英文摘要 | The rydberg and autoionization rydberg spectrum of scandium via intermediate state [ar] 3d4s4p f-2(5/2) have been measured in the energy region 52 625-54 046 cm(-1) using two-laser resonance excitation. four autoionization rydberg series are observed. eigenquantum defects mu(alpha) and transformation matrices u-i alpha are calculated from first principles by relativistic multichannel theory within the framework of multichannel quantum defect theory, while the dipole matrix elements d-alpha are obtained by comparing with experimental data. with these parameters mu(alpha), u-i alpha and d-alpha, rydberg and autoionization rydberg spectrum of scandium are calculated and the experimental peaks are then clearly assigned. more specifically, one autoionization rydberg series is converged to sc+ 3d4s d-3(3), the other three series are converged to sc+ 3d4s d-1(2), and one autoionization state converging to sc+ 3d(2)(f-3(2)) and/or sc+ 3d(2)(d-1(2)) are assigned. in addition, the fano parameters e-r, q, and gamma for some of these states are fitted and analyzed. |
