摘要：

We present results of an eigenchannel R-matrix calculation of the photoabsorption spectrum of He below He+(n = 3) hold. The observed n{upsilon}m(A) =3 {1}4+ resonance is found to decay with an 84.4% branching ratio to the 2{1}o ('2pepsilond') channel, in violation of a radial correlation propensity rule, DELTAA = 0. The DELTAupsilon = 0 propensity rule is satisfied, however, indicating that angular correlation is preserved in the decay of this resonance.
