Spin-polarized density functional theory studies of hydrogen sulfide (H 2 S) adsorption and decomposition on Ni(100) and Ni 3 Al(100) surfaces were conducted to understand the aluminum (Al) alloying effect on H 2 S dissociation. For such purpose, we first determined the near surface structure of fully ordered Ni 3 Al alloy along the (100) direction by calculating the Al segregation energy to.

We perform a systematic study on the spin decomposition of an electron in QED at one-loop order. It is found that the electron orbital angular momentum defined in Jaffe-Manohar and Ji spin sum rules agree with each other, and the so-called potential angular momentum vanishes at this order. The calculations are performed in both dimensional regularization and Pauli-Villars regularization for.

The decomposition of nuclear symmetry energy into spin and isospin components is discussed to elucidate the underlying properties of the NN bare interaction. This investigation was carried out in the framework of the Brueckner-Hartree-Fock theory of asymmetric nuclear matter with consistent two and three body forces. It is shown the interplay among the various two body channels in terms of.

Keywords: spin trap, CYPMPO, water decomposition radical. Abstracts. In the previous work we reported the rate constants of the reaction of a novel spin trap CYPMPO (5-(2,2-dimethyl-1,3-propoxy cyclophosphoryl)-5-methyl-1-pyrroline N-oxide) towards water decomposed species, e-aq and OH radical. In the present study we have detected these radicals as spin adducts of CYPMPO by ESR and.

Abstract: We analyze the problem of spin decomposition for an interacting system from a natural perspective of constructing angular momentum eigenstates. We split, from the total angular momentum operator, a proper part which can be separately conserved for a stationary state. This part commutes with the total Hamiltonian and thus specifies the quantum angular momentum.

In a recent paper, we have shown that the way of gauge-invariant decomposition of the nucleon spin is not necessarily unique, but there still exists a preferable decomposition from the observational viewpoint. What was not complete in this argument is a fully satisfactory answer to the following questions. Does the proposed gauge-invariant decomposition, especially the decomposition of the.
