Vibrational Spectra of Transition Element Compounds
1986Laser-ablated scandium atoms react with H2O/N2 mixtures to give matrix-trapped (η1-N2)Sc(H)OH, (η1-N2)2Sc(H)OH and (η2-N2)Sc(H)OH.

Quadratic isoparametric elements as transition elements
Engineering Fracture Mechanics, 1986Abstract The use of the quadratic isoparametric elements as transition elements is presented. It is shown that good estimates for the stress-intensity factor solution can be obtained over a wide range of the quarter-point element length over the crack-length ratio, provided that the aspect ratio between the transition element and the quarter-point ...

The invention relates to a transition element (1) for use between two line systems having different connection elements. The aim of the invention is to be able to utilize the advantages of plug-in screw fittings in vacuum technology. To this end, a vacuum flange adapter (2) is used for the purpose of connecting a first line system comprising small ...

Matrix Elements in Radiative Transitions
Proceedings of the Physical Society. Section A, 1953The matrix elements occurring in the theory of radiative transitions of electrons and positrons for a case of spherical symmetry are expanded in the general case as a series of radial integrals with known coefficients.

Superconductivity of transition elements
Physics Letters, 1962Garland (Proc. VIIIth Int. Conf. on Low Temperature Physics, London, 1962) has suggsted that the Coulomb interaction between the s electrons is screened in transition metals by the s-d electron cloud. He introduced a dielectric constant epsilon (q, omega ), and using a very specific model, he was able to prove that in a certain domain epsilon (q, omega

Other Transition-metal Elements
1971A Mossbauer resonance is known in at least one isotope of fourteen transition metals in addition to iron. However, none has been extensively used up to the present time. Several of them present extreme difficulties in measurement, but as this chapter will show, sufficient background information has been collected to assess the feasibility of chemical ...
