We study the ground state and low-lying excitations of the S ΒΌ 1 2 XXZ antiferromagnet on the kagomeΒ΄lattice at magnetization one-third of the saturation. An exponential number of non-magnetic states is found below a magnetic gap. The non-magnetic excitations also have a gap above the ground state,

Potential curves for the X 2~g, A 2~u, B 2 C: and C 2x; electronic states of BO2 were calculated at ab initio SCF RHF and confiiuration Interaction (CI) level. The results obtained are consistent with a linear molecular model for all states considered. The calculated structural parameters and transi
The electronic structure of the ground state and electronic transition energies of low-lying states have been calculated using the INDO/S-CI method for MosX,(aq) :' cluster ions (X=0, S). It has been shown that the calculated values are in accordance with those observed experimentally, allowing us t
