Abstract
The authors present results of an eigenchannel R-matrix calculation of the photoabsorption spectrum of He below the He+ (n=3) threshold. The observed n(v)mA=3{1}4+ resonance is found to decay with an 84.4% branching ratio to the 2{1}0 ('2p epsilon -d') channel, in violation of a radial correlation propensity rule, Delta A=0. The Delta v=0 propensity rule is satisfied, however, indicating that angular correlation is preserved in the decay of this resonance.Keywords
