摘　　要：By combining the B-spline basis set with model potential (B-spline + MP),we present oscillator strengthspectra of Rydberg Li atoms in external fields.The photoabsorption spectra are analyzed.Over the narrow energyranges considered in this paper,the structure of the spectra can be independent of the initial state chosen for a givenatom.Our results are in good agreement with previous high-precision experimental data and theoretical calculations,where the R-matrix approach together with multichannel quantum defect theory (R-matrix+MQDT) was used.It issuggested that the present methods can be applied to deal with the oscillator strength spectra of Rydberg atoms incrossed electric and magnetic fields.
