利用四束共传播的行激光束组成的原子干涉仪，观察了直流电斯塔克效应引起的原子波函数相移。我们计算了热原子束情况下干涉仪的干涉信号。将观测到的干涉条纹与计算得到的干涉条纹进行比较，得到$^{3}P_{1}$状态与$^{1}S_{0}$状态的极化率之差为$\ensuremath{\alpha}(^{3}P_{1})\ensuremath{-}\ensuremath{\alpha}(^{1}S_{0})=(13.4\ifmmode\pm\else\textpm\fi{}2.0)\ifmmode\ \else\texttimes\fi{}{10}^{\ensuremath{-}24}$ ${\ mathm {cm}}^{3}$。这个值与从斯塔克频移中推断出来的值一致。
We observed the phase shift of the atomic wave function induced from the dc Stark effect using an atom interferometer comprised of four copropagating traveling laser beams. We calculated the interference signal for the interferometer in the case of a thermal atomic beam. By comparing the observed interference fringes with the calculated ones, the difference between the polarizabilities of the $^{3}P_{1}$ state and the $^{1}S_{0}$ state of calcium was obtained to be $\ensuremath{\alpha}(^{3}P_{1})\ensuremath{-}\ensuremath{\alpha}(^{1}S_{0})=(13.4\ifmmode\pm\else\textpm\fi{}2.0)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}24}$ ${\mathrm{cm}}^{3}$. This value was consistent with that deduced from the Stark frequency shift.
