Photoionization study of the F2+ion via the screening constant by unit nuclear charge method

In this paper, we have tabulated energy resonances of the 2s22p2 (1D)nd( 2L), 2s22p2 (1S)nd( 2L) and 2s22p3 (3D)np Rydberg series originating from the 2s22p3(2Po) and from the 2s22p3 (2Do) metastable states of F2þ. In addition, energy resonances of the 2s2p3(5So)np( 4P) Rydberg series originating from the 2s22p3 (4So) ground-state of F2þare also reported. Calculations are performed using the Screening constant by unit nuclear charge (SCUNC) method. Analysis of the present data is achieved by calculating the quantum defects and the effective nuclear charges for each series. The present results agree very well with the Advanced Light Source experiments on F2þ (Aguilar et al., 2005). Upto n¼30, the present quantum defects are almost constant and the effective charge decreases regularly toward the electric charge of the F3þ core ion along each series.
