摘要：

We have measured the angular distribution of electrons emitted in the autoionization of the giant resonance (3)p(6)4s(2)S --> [(3p(5)3d(1)P)4s]P-2 in Ca+ ions over the profile of the resonance. The absolute value of the asymmetry parameter we have determined at the top of the resonance is beta = 1.89 +/- 0.13, suggesting that LS coupling remains a good approximation for the description of this ionic resonance.
