Nontrivial boson representations of the Schwinger group W(3)

Schwinger's group W(3) is used to classify bosons as states consisting of two fundamental Fermi fields and a single Bose field. These states cannot decay into ordinary mesons, and in this sense they may be identified with charmed particles. A mass formula is derived for a nine-dimensional representation of the Schwinger group.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 7, pp. 109–111, July, 1981.     

Solid State Conductivity and Catalytic Activity of Hexacyanoferrate(II)–Thiosemicarbazide Complexes of 3d-Metals

The temperature dependence of the resistivity of tablets of hexacyanoferrate(II)–thiosemicarbazide complexes of chromium(III), manganese(II), iron(III), cobalt(III), nickel(II), copper(II), and zinc(II) was measured in the range 20-90 °C. A relationship between the conductivity of a substance and the rate constant for the catalytic decomposition of hydrogen peroxide is established.
