The lifetime broadening of some rare-earth {ital L}{sub III}-edge x-ray absorption spectra (XAS) is partially removed by deconvolving high quality data. The ligand field splitting of dipolar resonances is clearly resolved. Exposed pre-edge structure is compared to atomic multiplet calculations of the 2{ital p}{r_arrow}4{ital f} quadrupolar excitations. Ratios are thereby determined for the quadrupolar/dipolar oscillator strengths. Deconvolved XAS data of Ho(NO{sub 3}){sub 3} are compared to inelastic x-ray scattering measurements showing experimentally that the latter cannot reproduce a narrowed XAS. {copyright} {ital 1996 The American Physical Society.}
