First direct observation of isomeric decay in neutron-rich odd-odd Ta
Y. X. Watanabe, P. M. Walker, Y. Hirayama +19
De-excitation rays associated with an isomeric state of Ta were investigated. The isomers were produced in multinucleon transfer reactions between a Xe beam and…
Persistence of the shell gap in isobars: Identification of a possible s isomer in Co and decay to Ni
S. Escrig, A. I. Morales, S. Nishimura +40
Background: The evolution of shell structure around doubly magic exotic nuclei is of great interest in nuclear physics and astrophysics. In the `southwest' region of Ni, the…
Nuclear structure of 140Te with N = 88: Structural symmetry and asymmetry in Te isotopes with respect to the double-shell closure Z = 50 and N = 82
C. -B. Moon, P. Lee, C. S. Lee +42
We study for the first time the internal structure of 140Te through the beta-delayed gamma-ray spectroscopy of 140Sb. The very neutron-rich 140Sb, Z = 51 and N = 89, ions were prod…
Structural evolution in the neutron-rich nuclei 106Zr and 108Zr
T. Sumikama, K. Yoshinaga, H. Watanabe +44
The low-lying states in 106Zr and 108Zr have been investigated by means of β-γ and isomer spectroscopy at the RI beam factory, respectively. A new isomer with a half-life of 620\pm…
Magnetic and Metal-Insulator Transitions in beta-Na0.5CoO2 and gamma-K0.5CoO2 -NMR and Neutron Diffraction Studies-
H. Watanabe, Y. Mori, M. Yokoi +7
Co-oxides beta-Na0.5CoO2 and gamma-K0.5CoO2 have been prepared by the Na de-intercalation from alpha-NaCoO2 and by the floating-zone method, respectively. It has been found that su…
59Co-NMR Knight Shift of Superconducting Three-Layer NaxCoO2.yH2O
H. Watanabe, Y. Kobayashi, M. Sato
The superconducting state of NaxCoO2.yH2O with three CoO2 layers in a unit cell has been studied by 59Co-NMR. The Knight shift measured for a peak of the NMR spectra corresponding…
