    Notes: Abstract Based on the geological background, R-mode factor statistics, and the analysis of the stability diagram for the corresponding system, five weathering reactions controlling the surface-water chemical composition in the watershed of the Changhuajiang River are deduced. In the mass balance model, the precipitation accounts for some solute input, since the rainwater is dilute without pollution. Most of the Ca2+ and HCO 3 − ions are from the dissolution of calcite, K+, Na+, H4SiO4 and some of the Mg2+ and HCO 3 − come from albite and biotite weathering to kaolinite. The dissolution of dolomite and gypsum controls the mass balances of Mg2+ and SO 4 2− . The dissolution of calcite is the dominant chemical weathering reaction in the watershed because of its reactivity and high concentration. In the watershed in 1986, the chemical weathering rate was 0.073 (kg/m2 a), and the mechanical denudation rate is 0.093 (kg/m2 a). The chemical weathering mass output proportion of carbonate rocks to silicate rocks was about three to one.

Hagakawa High-spin states of 80 Rb are studied via the fusion-evaporation reactions 65 Cu+ 19 F, 66 Zn+ 18 O, and 68 Zn+ 16 O with the beam energies of 75 MeV, 76 MeV, and 80 MeV, respectively. Twenty-three states with twenty-eight γ transitions are added to the previously proposed level scheme, where the second negat... [Phys. Rev. C 87, 034320] Published Fri Mar 22, 2013
