We have performed neutron inelastic scattering and resonant inelastic X-ray scattering (RIXS) at the Cu-
edge to study high-energy magnetic excitations at energy transfers of more than 100 meV for overdoped LaSrCuO with 
= 0.25 (
= 15 K) and = 0.30 (nonsuperconducting) using identical single-crystal samples for the two techniques. Our results indicate consistency between neutron inelastic scattering and RIXS, and elucidate the entire magnetic excitation in the 
direction by the complementary use of two probes. The paramagnon along 
agrees well with the LCO spin-wave dispersion, while the paramagnon in the direction probed by RIXS appears to be less dispersive.
