Oscillator strengths of some higher Cs principal series lines

Abstract
The oscillator strengths of the principal series doublet of Cs f3/2(62S1/2-n2P3/2, 151/2(62S1/2-n2P1/2, 153/2/f1/2 was found to increase monotonically with the principal quantum number n. From an extrapolation of the relevant Fano function a maximum in the ratio rho should not be expected for higher n.
