N2 - The high-energy phonons in La1.5Sr0.5NiO4, in which the checkerboard charge ordering is formed, was investigated by the inelastic neutron scattering. We found that the longitudinal modes show strong anomalies compared with La2NiO4. We argue the similarity and difference in the phonon anomalies between the present sample and the preceding works of different compositions.
