The Atomic Volume of Hydrogen in Metal Hydrides in Comparison with Corresponding Fluorides and Chlorides The atomic volume of hydrogen in metal hydrides is calculated by using the atomic volumes of the metal cations as given by Biltz. The exceptional polarizability of hydrogen ligands is the reason for its adaptability when forming different bond structures in metal hydrides. The atomic volume of hydrogen decreases from 13.7 cm3mol?1 in salt-like caesium hydride to 3.9 cm3mol?1 in metallic palladium hydride. This variation is significantly higher for metal hydrides than for metal chlorides, although the volume of a hydrogen ion is comparable to that of a fluoride ion, that shows an almost constant value in its compounds. For structurally related hydrides an examination of the atomic volume of hydrogen allows the re-examination of a given composition and therefore the disclosure of a wrong atomic arrangement. 相似文献

High-spin states of 95,97Mo (Z=42, N=53,55) nuclei have been investigated through 82Se(18O, xn) reaction at Eb=60 MeV. The level scheme in 95Mo has been observed upto ≏ 10 MeV in the present experiment. The level structure shows mainly single particle character.
In 97Mo, the ground state level sequence has been extended to ≏ 4.5 MeV while the previous information had been up to 2.4 MeV.
A negative parity band built on 1437 keV (11/2−) excited state has been extended to 5.5 MeV. The structure seems to show a coexistence of single particle and collective
modes of excitation. Properties of both the nuclei have been compared with shell model calculations using OXBASH. 相似文献

The nucleus 30 65 Zn was studied using the 52Cr(16O, 2pn)65Zn reaction at a beam energy of 65 MeV. The level scheme is extended up to an excitation energy of 10.57 MeV for spin-parity (41/2?) with several newly observed transitions placed in it. 相似文献

Na3AsSe3 and K3AsSe3 – Synthesis and Crystal Structure The compounds Na3AsSe3 and K3AsSe3 were synthesized by heating mixtures of As2O3 and the respective alkalicarbonate in a stream of hydrogen saturated by selenium at 750 °C. The structures were determined from X-ray single-crystal diffractometer data. Both compounds crystallize isostructural with Na3AsS3, space group P213, Z = 4, lattice constants a = 8,925 (1) Å for Na3AsSe3 and a = 9,710(1) Å for K3AsSe3. 相似文献
