Impurity-concentration dependence of internal magnetic field acting on platinum in ferromagnetic iron metal

It was found by perturbed angular correlation that the internal magnetic fields acting on platinum in iron were kept in a definite value for uniform alloy samples with impurity concentration ranging from 2 at% to 0.1 at%. Theg-factor of 355.7 keV level of¹⁹⁶Pt was revised tog=0.335±0.018 using the refined ωτ.     

Optical absorption of small metallic particles

In an extremely small metallic particle in which electron energies take discrete values, a light is absorbed by the surface plasmon which is not decayed by the surface scattering. The usually used relation between polarizability of a particle and electrical susceptibility does not hold.     

Nuclear g-factor of the 172+ isomeric state in 63Cu

The nuclear g-factor of the 4498 keV $\text{17}\text{2}$⁺ isomeric state in ⁶³Cu was measured with the in-bearn perturbed angular distribution method, through the ⁶²Ni(α, p2nγ)⁶³Cu reaction, to be g_exp = 0.184 ± 0.012. This value is in good agreement with a semiempirical g-factor for the three-quasiparticle configuration [π2p_{$\text{3}\text{2}$}(v1f_{$\text{5}\text{2}$}, 1g_{$\text{9}\text{2}$})₇]_{$\text{17}\text{2}$⁺} calculated using the experimental single-particle g-factors of neighbouring nuclei. At the same time the internal magnetic field at the Cu nuclei in Ni metal was obtained to be B_int = ?46.6 ± 1.3 kG.     

Photo-induced magnetophonon resonance in n-InSb at 4.2°K

Spin-flip and two-phonon as well as normal magnetophonon resonance are observed in CO₂-laser-irradiated photoconductivity in n-InSb at 4.2°K. The effects are attributed to the resonant cooling of photo-excited electrons due to optical phonon emission.     

Raman scattering and bond structure in chalcogenide glasses (SeGe system)

The Raman Scattering from amorphous SeGe is studied in the whole range of germanium content up to 80%. The result suggests an appearance of three-fold coordinated bond between Se and Ge above the germanium con- content of 40%.
