摘要
Similar to most of the other alkaline earth elements,barium atoms can be candidates for optical clocks,thus the magic wavelength for an optical lattice is important for the clock transition.We calculate the magic wavelength of a possible clock transition between 6s21S0 and 6s5d3D2 states of barium atoms.Our theoretical result shows that there are three magic wavelengths 615.9 nm,641.2 nm and 678.8 nm for a linearly polarized optical lattice laser for barium.
