Times Cited Count：54 Percentile：13.41(Materials Science, Multidisciplinary)Phonons along the [100] direction, in particular the highest energy Cu-O bond-stretching LO mode, of LaSrCuO have been studied by inelastic X-ray scattering experiments. The LO phonon mode in the 
= 0.12 sample shows significant softening similar to early neutron studies. We show here a recovery of the softening was found in the = 0.29 sample, where superconductivity degrades and normal metallic conductivity dominates. The results suggest one-to-one correspondence between the softening of this LO phonon and the superconductivity.

Inelastic neutron scattering measurements have been performed on superconducting NaHfNCl powder samples with x=0.27 and 0.38 (T =22 K). We have observed several temperature dependent phonon anomalies, e.g., at E=15, 29, 76, and 81 meV for the former sample. A phonon peak with E=14.5 meV at Q=6 
increases for both samples with decreasing temperature below T=40 K, which is much higher than T. The phonon peak is assigned to an ab-plane vibrational mode, E
, of chlorine and hafnium atoms, which strongly modifies the electronic band structure. The phonon anomaly is discussed in terms of carrier inhomogeneity.

Times Cited Count：8 Percentile：48.36(Instruments & Instrumentation)We evaluated the neutron--rays discrimination of the neutron detector comprising a superconducting tunnel junction (STJ) on the single crystal of LiBO. The neutron detector was irradiated with X-rays, -rays and neutrons, and the signal pulses were analyzed including pulse height distributions and rise times. It was found that the most of the signal pulses for the neutron-events exhibited slower rise times than those for X-rays and -rays. This indicated the capability of neutron--rays discrimination of the detector using the differences in the decay time of the signal current.
