Lifetime-broadening-suppressed x-ray absorption near edge structure (LBS-XANES) spectroscopy is applied to the Dy L{sub 3} edge, where multiplet nature of the final state as well as lifetime-broadening distorts the band shape. It was found that, by determining appropriate final state density function from observed the L{alpha} band shape, LBS-XANES spectra can be obtained and 2p{yields}4f quadrupole transition is unequivocally observed as a separate peak. It has been proved from the present results that LBS-XANES spectroscopy is very versatile; transitions with multiplet final states can be studied by the use of hard x-rays and forbidden transitions obscured by intense dipole-allowed transitions can be revealed. Implications for resonant inelastic x-ray scattering (RIXS) spectra are also discussed in terms of RIXS contour plot and the Kramers-Heisenberg equation.
