The microwave spectra of four isotopic species of dichlorine monoxide (OCl2) have been observed, and the rotational constants have been obtained. The rm structure for each isotopic species has been determined by Watson's method. The equilibrium structure has been estimated by taking proper averages of rm structures to be and ∠eClOCl = 110.886(6)°. The general applicability and the merit of the present method for estimating the equilibrium structure are pointed out. 相似文献

Intrinsic mechanism of pair breaking is given for dirty superconducting films. Dynamical interaction between electrons such as Coulomb interaction plays an essential role. The diffusion processes of both density- and pair-fluctuations are also important. The problem of the Thompson's parameter for the Maki term of fluctuation conductivity is solved and the correct dependence of the parameter of the sheet resistance Rsq is given. 相似文献

The spin‐gap phenomenon is a key characteristic of high Tc superconducting cuprates, whose experimental results are summarized and discussed in the context of the slave‐boson mean
field theory of the extended t–J model. It is seen that there exists satisfactory agreement between theory and experiments
in bilayer cuprates. As regards the apparent absence of the spin‐gap in single layer La2-xSrxCuO4 (LSCO), the possible roles played by disorder have been pointed out in view of the recent neutron scattering experiment on
other spin singlet systems, the spin‐Peierls CuGeO3 and two‐leg ladders.
This revised version was published online in July 2006 with corrections to the Cover Date. 相似文献

We consider Kaluza-Klein theory based on the fiber bundle. We obtain the modified Kaluza-Klein metric as an invariant line element of a bundle. Its reduced action includes a higher derivative action in gravitation as well as a term linear inR. 相似文献

Orbital magnetic moment and the frequency dependent conductivities of the Wigner crystal are examined in the harmonic approximation. The effects of scattering on the collective modes are also discussed. 相似文献
