Abstract

Combined with a collimated atomic beam source, diode laser without external cavity has been used as a spectroscopic light source to study atomic hyperfine structures and isotope shifts of Ba I. Spectroscopic measurements of the 6s^{2 1}S₀ - 6s6p ³ P₁ transition of Ba I have been carried out. All hyperfine peaks of Ba have been clearly seen and resolution of 50MHz has been attained. Hyperfine constants A and B of the ³P₁ state of ^135,137Ba have been determined. Isotope shifts of stable Ba isotopes have also been measured. From the measured isotope shifts, the 6s electron density at the nucleus has been deduced to be 76.4(53) a.u. and discussed in terms of the Hartree-Fock approximation.
