Effect of the three-body force on trinucleon bound systems consideringS andS′-state admixture

We report the calculation of binding energy, charge form factor and point-like proton density of both³H and³He by the hyperspherical harmonics method with the inclusion of two-pion exchange three-nucleon force (Fujita-Miyazawa type). For the two-body force theN-N Afnan-Tang S-3 potential is taken. Coulomb and three-body forces are treated nonperturbatively. In this calculation the mixed symmetryS′-state of the trinucleon ground state is considered along with the space totally symmetricS-state.     

Das thermische Verhalten einiger “Prussiate”

The air oxidation of copper sheets was followed by thermogravimetry in order to establish the formation of copper(II) oxide and to determine the activation energy of the copper(I) oxide — copper(II) oxide transition. The results were compared with those obtained by using the isothermal procedure.     

Coherent amplification in fluorescent dye solutions. II. The inverse pre-resonance Raman spectrum of rhodamine 6G

Inverse pre-resonance Raman spectra of rhodamine 6G in solution in methanol have been recorded over the concentration range 10^?1 to 10^?4 mol ?^?1. The solute and solvent transitions are found to display perfectly normal lorentzian profiles over the whole of this concentration range. Intensities and depolarization ratios of the pre-resonance Raman features are recorded. It is shown that the spectra arise from monomeric rhodamine 6G molecules in the singlet electronic ground state and the relative merits of the CARS and inverse Raman methods for recording resonance Raman spectra are discussed.     

Vibrational spectrum of RbVOPO4

The infrared and Raman laser spectra of RbVOPO₄ were recorded and briefly discussed with the aid of factor group analysis. Some comparisons with the spectra of related materials were also made.     

Das Schwingungsspektrum von Li5ReO6

The infrared and laser-Raman spectra of crystalline Li₅ReO₆ are reported and discussed and some comparisons with other lithium hexaoxometallates are made.     

Electronic spectrum and magnetic properties of the Ni(II) telluromolybdate

The room temperature electronic (reflectance) spectrum and the magnetic properties of NiTeMoO₆ in the temperature range 100 – 300 K were investigated in order to obtain a wider insight into the structural properties of the M^IITeMoO₆-type telluromolybdates. The results show that Ni(II) is located in a distorted octahedral environment and that there are important orbital contributions to the magnetic moment. Some data for CdTeMoO₆ and CoTeMoO₆ are also reported.     

Electron paramagnetic resonance of impurities in uranium trichalcogenides

Uranium trichalcogenides US₃ and UTe₃ were examined by EPR. The measurements were performed at the X-band over temperature range 4.2–300K and with the magnetic field applied perpendicular and parallel to the (001) plane. The EPR spectra consist of two lines with g-factors about 2 and 4 respectively. Results are discussed in terms of interactions of the U⁴⁺ ion with impurities. A magnetic ordering in US₃ below 50 K is suggested.
