For a mixture of alkali-earth atomic gas in the long-lived excited state 3P0 and ground state 1S0, in addition to nuclear spin, another "orbital" index is introduced to distunguish these two internal states. We propose a mechanism to induce Feshbach resonance between two atoms with different orbital and nuclear spin quantum numbers. Two essential ingredients are inter-orbital spin-exchanging scattering and orbital dependence of hte Land e g-factors. Here the orbital degrees of freedom plays similar role as electron spin degree of freedom in magnetic Feshbach resonance in alkali-metal atoms. This resonance is particularly accessible for 173Yb system.
