Spin polarization of the Ar * 2 p - 11 / 2 4 s , and 2 p - 11 / 2 3 d resonant Auger decay

Interatomic Coulombic decay following resonant core excitation of Ar in argon dimer.

A scheme utilizing excitation of core electrons followed by the resonant-Auger - interatomic Coulombic decay (RA-ICD) cascade was recently proposed as a means of controlling the generation site and energies of slow ICD electrons. This control mechanism was verified in a series of experiments in rare gas dimers. In this article, we present fully ab initio computed ICD electron and kinetic energy...

Spin resolved photoelectron spectroscopy of [Mn6(III)Cr(III)]3+ single-molecule magnets and of manganese compounds as reference layers.

Properties of the manganese-based single-molecule magnet [Mn(6)(III)Cr(III)](3+) are studied. It contains six Mn(III) ions arranged in two bowl-shaped trinuclear triplesalen building blocks linked by a hexacyanochromate and exhibits a large spin ground state of S(t) = 21/2. The dominant structures in the electron emission spectra of [Mn(6)(III)Cr(III)](3+) resonantly excited at the L(3)-edge ar...

Using three point QCD sum rules method, the form factors relevant to the semileptonic Bs → DsJ(2460)lν decay are calculated. The q2 dependences of these form factors are evaluated and compared with the heavy quark effective theory predictions. The dependence of the asymmetry parameter α, characterizing the polarization ofDsJ meson, on q2 is studied. The branching ratio of this decay is also est...

Explicit expressions for the parity-violating s-wave and the parity-conserving p-wave contributions to π− weak-decay rates of Λ hypernuclei in the 1p shell are given in the weak-coupling limit, to update previous shell-model calculations and to compare with recent π− spectra and total decay rates measured by the FINUDA Collaboration for ΛLi, 9 ΛBe, 11 ΛB and 15 ΛN. A useful sum rule for the sum...
