a–d The normalized atomic phase shift distributions, \({{\Delta }}{\phi }_{{{{{{{{\rm{rel}}}}}}}}}^{{{{\Theta }}}_{{{{{{{{\rm{T}}}}}}}}}}(\theta )\), in units of π radians as a function of the photoelectron emission angle of helium at a skew-angle of ΘT = (a) 0∘, (b) 20∘, (c) 54. 7∘, and (d) 90∘. The triangles and solid lines show the experimental and theoretical results, respectively. The error bars in the experimental results represent the standard deviation. The shaded area indicates the fitting error uncertainty and the line colors are weighted by the yield of the photoelectron angular distribution. e–h, i–l As a–d but for the SB18 of neon and SB14 of argon, respectively.
