摘要：

The lifetime broadening of some rare-earth L(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 2p-->4f quadrupolar excitations. Ratios are thereby determined for the quadrupolar/dipolar oscillator strengths. Deconvolved XAS data of Ho(NO3)(3) are compared to inelastic x-ray scattering measurements showing experimentally that the latter cannot reproduce a narrowed XAS.
