Temperature Action

We present the long-wavelengths/low-frequencies action of a two-dimensional quantum Heisenberg antiferromagnet of general spin magnitude s on a triangular lattice which describe the fluctuations around the ordered Neél ground state. This action is a nonlinear σ-model whose configuration space is the SO(3) manifold, in this respect being different from the usual S2 σ-model which models an antiferromagnet on a bipartite lattice. We present a map on a O(4)-model which allows to study the properties of the system.

Vuv Spectra

Using R.D. Cowan’s computations (1979) and parametric calculations of Meinders et al (1982), old analyses are thoroughly revised and extended at Aligarh, of Zr III by Khan et al (1981), of Nb IV by Shujauddin et Chaghtai (1985), of Mo V by Tauheed at al (1985). Cabeza et al (1986) confirmed the last one largely.Extensive studies have been reported of the 1–e spectra, Zr IV (Rahimullah et al 1980; Acquista and Reader 1980), Nb V (Shujauddin et al 1982; Kagan et al 1981) and Mo VI (Edlén et al 1985). Some interacting 4p54d2levels of these spectra have been reported from our laboratory, also.Detailed spectral analyses of transitions between excited states have furnished complete energy values for J ≠ 1 levels of these spectra during 1970s and 80s. Shujauddin et al (1982) have worked out Nb VI and Tauheed et al (1984) Mo VII from our lab, while Khan et al (1981) share the work on Zr V with Reader and Acquista (1979).
