Isotope-selective photoionization spectroscopy of barium

Darrell J. Armstrong, J. Cooper

We demonstrate an experimental technique that selects the nuclear spin I=0 isotope $^{138}\mathrm{Ba}$ for spectroscopic measurements from a beam of natural barium containing seven stable isotopes. A cw dye laser is used to optically pump the I=3/2 isotopes $^{135}\mathrm{Ba}$ and $^{137}\mathrm{Ba}$ into the metastable 6s5d $^{1}$ ${\mathit{D}}_{2}$ and $^{3}$ ${\mathit{D}}_{1,2}$ levels via the 6s6p $^{1}$ ${\mathit{P}}_{1}$ excited state, leaving nearly pure $^{138}\mathrm{Ba}$ in the ground state. Photoionization spectra of the excited 5d6p $^{3}$ ${\mathit{D}}_{1}$ even isotope state recorded with optical pumping of $^{135}\mathrm{Ba}$ and $^{137}\mathrm{Ba}$ to the metastable levels are essentially devoid of forbidden features associated with the hyperfine interaction in the odd isotopes.We demonstrate an experimental technique that selects the nuclear spin I=0 isotope $^{138}\mathrm{Ba}$ for spectroscopic measurements from a beam of natural barium containing seven stable isotopes.
