First direct measurements are reported of the linear reduced Stokes parameters (P) over bar(1),(P) over bar(2) for H(2p) excited by electron impact at the benchmark energy of 54.4 eV. The results differ significantly from previous values deduced from angular correlation measurements which are in serious conflict with all sophisticated theoretical approaches. Our results support the trend of theoretical predictions for (P) over bar(2) and confirm that its value is negative at electron scattering angles above 100 degrees, as predicted by theory.
