摘要：
Starting from the He-2(a) state absorption and induced fluorescence experiments were performed using a narrow band dye laser. The saturation intensity for the He-2(e)<--He-2(a) transition yields a radiative lifetime of tau = (67 +/- 10) ns. Time resolved measurements of the laser induced fluorescence yield the radiative lifetimes for the states He-2(e): (57 +/- 10) ns, He-2(d): (25 +/- 5) ns and He-2(f): (19 +/- 5) ns. From the time integrated fluorescence data the collisional quenching rates between the above states were determined.
