Study on radiative decays of and into by means of LFQM
The observed resonance peak around 2.86 GeV has been carefully reexamined by
the LHCb collaboration and it is found that under the peak there reside two
states and which are considered as
and with slightly different masses and
total widths. Thus, the earlier assumption that the resonance
was a state should not be right. We suggest to measure the partial widths
of radiative decays of and to confirm their
quantum numbers. We would consider as or a pure
state, or their mixture and respectively calculate the corresponding
branching ratios as well as those of . The future precise
measurement would provide us information to help identifying the structures of
those resonances .Comment: 8 pages, 4 figures, 1 tabl
Chlorido{μ-2,6-bisÂ[(2-aminoÂethÂyl)iminoÂmethÂyl]-4-chloroÂphenolato}-μ-oxido-dicopper(II) trihydrate
In the title dinuclear complex, [Cu2(C14H20ClN4O)ClO]·3H2O, one CuII cation assumes a distorted square-planar coordination geometry and the other a distorted square-pyramidal coordination geometry. Both CuII cations are N,N′,O-chelated by one arm of the 2,6-bisÂ[(2-aminoÂethÂyl)iminoÂmethÂyl]-4-chloroÂphenolate anion, and one oxide anion bridges the two CuII cations, forming a dinuclear complex. One of the CuII cations is further coordinated by an Cl− anion in the apical direction. In the crystal, lattice water molÂecules are linked with the complex molÂecule via O—H⋯Cl hydrogen bonds while O—H⋯O hydrogen bonding occurs between lattice water molÂecules , forming three-dimensional network structure
