摘      要：Sixty-five new vibronic levels of the Na2 4^3∑g^＋ state have been observed in the 33900-35200 cm^-1 energy region above the potential minimum of the ground state by pulsed perturbation facilitated optical-optical double resonance （PFOODR） fluorescence excitation spectroscopy. These new data fill the gap between the low-v levels mainly observed by continuous wave （CW） PFOODR spectroscopy and the high-v levels above the 3s＋3d limit observed by pulsed PFOODR with predissociation detection, Molecular constants are fitted below potential shelf around the 3s＋3d atomic limit with previously published data （mainly observed by CW PFOODR） and these new data. RKR potential curve has been calculated with the new constants. The constants are： Te= 32127.090 cm^-1,ωe=121.4099（0.20720） cm^-1, Be = 0.116287（0.0002300） cm^-1, Re=3.551 A, An error of the RKR potential curve of J. Chem. Phys. 108, 7707 （1998） is corrected.
