3-Fluorobenzoic acid–4-acetylpyridine (1/1) at 100 K
In the title compound, C(7)H(5)FO(2)·C(7)H(7)NO, a moderate-strength hydrogen bond is formed between the carboxyl group of one mol-ecule and the pyridine N atom of the other. The benzoic acid mol-ecule is observed to be disordered over two positions with the second orientation only 4% occupied. This disorder is also reflected in the presence of diffuse scattering in the diffraction pattern.
متن کاملStudies of Three-Body B^+→D ̅^* 〖(2007)〗^0 K^+ K ̅^0 and B^0→D^* 〖(2010)〗^- K^+ K ̅^0 Decays
We analyze three-body decays of and . Under the factorization approach, there are tree level diagrams for these decay modes and the transition matrix element of decay is factorized into a form factor multiplied by decay constant and form factor multiplied into weak vertices form factor. The transition matrix element of decay is also factorized into a form factor multiplied into weak vertic...
متن کاملبررسی سینتیک و سازوکار سنتز NH3 بر سطح کاتالیستهای مدل Fe(100) و K/Fe(100)
In this investigation kinetics and mechanism of NH3 synthesis over Fe(100) and K/Fe(100) model catalysts have been studied. In this context, adsorption kinetics of both N2/Fe (100) and H2/Fe (100)systems is initially investigated. By using statistical mechanic approach, we have determined the adsorption coefficient for N2 and H2 molecules as well as transition probability of different states ...
متن کامل1 B → K ∗ γ decay on APE ∗
We present results for the radiative decay B → K * γ, obtained by using the Clover action at β = 6.0 on APE. The compatibility between the scaling laws predicted by the Heavy Quark Effective Theory (HQET) and pole dominance is discussed. The final result depends crucially on the assumed q 2-dependence of the form factors.
متن کاملMeasurement of B ( K + → π + νν ) 1
The experimental measurement of K→πνν is reviewed. New results from experiment E787 at BNL are presented: with data from 1995–97 the branching ratio has been measured to be B(K→πνν ) = (1.5 −1.2) × 10 . The future prospects for additional data in this mode are examined.
