Photoelectron branching ratios and angular distributions have been measured for the six outermost levels of BF₃ in the range 17≤ hν≤ 28 eV with the use of synchrotron radiation. Comparisons are made with a recent multiple-scattering model calculation which indicates that a shape resonance in the e' electronic continuum should appear in five of the six channels studied. Good agreement between experiment and theory is found in a majority of the comparisons; however, experimental evidence for the expected e' shape resonance is clear in some cases but absent in others. The results are discussed in the context of other cases in which shape resonances, well known from inner-shell spectra, are obscured in valence-shell properties. Experiments which would help clarify the role of the e shape resonance in the photoionization dynamics of BF₃ are suggested.
