Times Cited Count：10 Percentile：69.3(Physics, Multidisciplinary)Direct proton-knockout reactions of 
Sc were studied at the RIKEN Radioactive Isotope Beam Factory. Populated states of Ca were investigated through 
-ray and invariant-mass spectroscopy. Level energies were calculated from the nuclear shell model employing a phenomenological inter-nucleon interaction. Theoretical cross sections to states were calculated from distorted-wave impulse approximation estimates multiplied by the shell model spectroscopic factors. Despite the calculations showing a significant amplitude of excited neutron configurations in the ground-state of Sc, valence proton removals populated predominantly the ground-state of Ca. This counter-intuitive result is attributed to pairing effects leading to a dominance of the ground-state spectroscopic factor. Owing to the ubiquity of the pairing interaction, this argument should be generally applicable to direct knockout reactions from odd-even to even-even nuclei.

Longitudinal and transverse wave velocities, five kinds of elastic moduli, Debye temperature and Gruneisen parameter have been simultaneously measured as functions of temperature from 298 to 1764 K in polycrystalline MgO, by help of aluminum couplant. Young, shear, bulk moduli, and Gruneisen parameter and Poisson's ratio decreased and increased monotonically with increasing temperature, respectively, showing a lowering of ionic bonding strength. Lame parameter versus temperature slope is almost zeroing in the whale temperature region. The behavior was interpreted as an interlocking associated with network of short Mg-O bonds, based on three-dimensional volume-nonpreserving shear.

It is unclear whether natural circular dichroism (NCD) originating from core-absorption of atoms located at various sites, as well as next to the asymmetric carbon, in the molecules can be observed selectively. In this study, we measured NCD spectra of an amino acid, histidine (His) which has three nitrogen atoms, thin film in the nitrogen K-edge energy region and confirmed whether we can pick up the NCD signals originating from each nitrogen atom throughout the molecules. NCD peaks assigned to the 1s 
of the nitrogen atoms in imidazole ring and the 1s 
transition of the nitrogen atoms in imidazole ring and amino group. Imidazole ring and amino group are positioned at the side chain distant from and next to the asymmetric carbon, respectively. This result suggests that NCD spectroscopy in the soft X-ray region can selectively pick up the information on local structure around specific atoms, regardless of the position of atoms in molecules.
