Screening Constant by Unit Nuclear Charge Photoionization of Rb\(^{2+}\) Ions

“…The present SCUNC calculations are listed in Tables 1-5 [20][21][22]; Ba et al [23]; Badiane et al [24]). Table 1.…”

“…Ba et al [23]; Badiane et al [24]). In the present work, all the energy resonances are calculated using the following simple expression (in Rydberg units)…”

“…Although very good agreement are found between the DARC [17] and ALS measurements [19], calculations can be improved as maximum energy differences between theory and experiment at 0.008 eV are observed for the 4s 2 4p 4 ( 1 D 2 )nd and 4s 2 4p 4 ( 3 P 1 )nd Rydberg series. The motivation of this work is to use the Screening constant by unit nuclear charge (SCUNC) formalism (Sakho [20][21][22]; Ba et al [23];…”

Single Photoionization Study of Br3+ via the Screening Constant by Unit Nuclear Charge Method

“…The remaining f 1 -parameter is to be evaluated empirically using the ALS data of Macaluso et al, [15] for a given ( 2S+1 L J ) µl level with ν = 0. The empirical procedure of the determination of the f 1 -screening constant along with the corresponding has been explained in details in our previous works [11][12][13][14][16][17][18]].…”

“…The main motivation of the present work is to provide accurate high-lying energy resonances of Rydberg series of resonances due to 4p→nd and 4s→np transitions that may be useful guidelines for investigators focusing their studies on the photoionization of the Br 3+ ion. For this purpose, we apply the SCUNC method [11][12][13][14][16][17][18] to provide the first theoretical calculations of the energy resonances of the Rydberg series of resonances due to 4p→nd and 4s→np transitions converging respectively to the 4s 2 4p ( 2 P 3/2 ) and 4s4p 2 ( 4 P 3/2 , 2 D 5/2 ) series limits in Br 4+ . Analysis of the present results is achieved in the framework of the standard quantum-defect theory and of the SCUNC procedure by calculating the effective charge.…”
