Results are presented for the inverse processes of photoionization and electron-ion recombination of (h þ Ne viii$ Ne ixþ e) and (h þ Ne ix$ Ne xþ e) using the self-consistent unified method. The method employs an identical wave function expansion for both photoionization and recombination, and it includes both radiative and dielectronic recombination. Total, as well as level-specific, photoion...
Abstract Using electron-positron annihilation data samples corresponding to an integrated luminosity of 4.5 fb , collected by the BESIII detector in energy region between 4599.53\; \,{\rm{MeV}} and 4698.82\; we report first observations Cabibbo-suppressed decays \Lambda_c^+\to n\pi^+\pi^0 n\pi^+\pi^-\pi^+ Cabibbo-favored decay nK^-\pi^+\pi^+ with statistical significances 7....

We present an atomistic simulation of the cobalt hexammine(ii/iii) self-exchange reaction using path integral (PI) methods. We construct a simple force field for the system in its reactant state that includes parameters for both atom-atom interactions, and interactions with an explicit transferring electron represented in the PI framework. We then calculate the outer sphere free energy barrier ...
The light dependent energization of the thylakoid membrane was analyzed in isolated intact spinach (Spinacia oleracea L.) chloroplasts incubated with different concentrations of inorganic phosphate (Pi). Two independent methods were used: (a) the accumulation of [(14)C]5,5-dimethyl-2,4-oxazolidinedione and [(14)C] methylamine; (b) the energy dependent chlorophyll fluorescence quenching. The inh...
We present the first study of the vector (Wess-Zumino) current in tau(-)-->K-pi-K+nu(tau) decay using data collected with the CLEO III detector at the Cornell Electron Storage Ring. We determine the quantitative contributions to the decay width from the vector and axial vector currents. Within the framework of a model by Kühn and Mirkes, we identify the quantitative contributions to the total d...
An analytical treatment of the electron screening effect within an active-electron model is given for positronium formation from helium atoms. A first-order distorted wave approximation with correct boundary conditions is applied to evaluate the transition amplitude. In the range of impact energy for which the introduced perturbative approach is valid, both the total and differential cross sect...
A new ruthenium(ii) polypyridyl-platinum(ii) diethynyl triad containing 3-ethynylphenanthroline linked by platinum(ii) bis-tributylphosphine organometallics, Ru(ii)-Pt(ii)-Ru(ii), and platinum(ii) bis-ethynylphenanthroline complex has been prepared. The ruthenium(ii)-metal triads, Ru(ii)-M-Ru(ii) (M = Pt(ii) and Au(i)), showed typical MLCT absorption bands and a lowest energy pi-pi* absorption ...
