abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...

 In this work, total excitation cross section of atomic hydrogen in the collision of bare ion was calculated employing a three body Faddeev formalism. In the present calculation, initially the first order electronic amplitude was calculated using the interaction potential which led to inelastic form factor. Secondly, the first order nuclear amplitude was calculated and added to the first order ...

 Coupled-channels Faddeev-Yacubovsky as well as AGS calculations of three-body, J π =0¯ K(NN)I=1(I=1/2) quasibound state in the KNN- πΣ N system were performed in momentum space and the dependence of the three-body energy on the two-body KN- πΣ interaction was investigated.

Base on the non-relativistic Faddeev AGS method, three-body calculations of the coupled and quasi-bound KKN-πKΣ system are performed in the momentum space. Different phenomenological models of KN-πΣ potentials with one and two-pole structures of KN-πΣ resonance are used to study the dependence of double-kaonic system binding energy on the coupled KN-πΣ interaction. Also, the effect of the KK  r...

  In this article nucleons are discussed based on constituent quark model. This model aims at studying the forces among three particles and the corresponding standard two-body potential contribution. The quark potential contains a hypercentral interaction. The confining potential is composed of four components,color charge, the oscillatory potential, the interaction quark and neutral gluon, and...
