We investigate Dirac's bra-ket formalism based on a rigged Hilbert space for non-Hermite quantum system with positive-definite metric. First, the space, characterized by metric, is established. With aid of nuclear spectral theorem obtained expansions are shown bra-kets generalized eigenvectors quasi-Hermite operator. The utilized to endow complete bi-orthogonal and transformation theory between...

Abstract We theoretically investigate the laser cooling of fermionic barium monofluoride ( 137 BaF) molecules, which are promising candidates for precision studies weak parity violation and nuclear anapole moments. This molecular species features two spins, resulting in a hyperfine structure that is considerably more complicated than one found usual laser-cooled diatomics. use optical Bloch equ...

We have performed an overall fit to the electroweak data with the generation blind U(1) extension of the Standard Model. As input data for fitting we have included the asymmetry parameters, the particle decay widths of Z, neutrino scattering, and atomic parity violation. The QCD coupling αs has been constrained to the world average obtained from all data except the Z width. On the basis of our ...

We employ stochastic modelling of statistical reactions with memory to study quasiperiodic oscillations in the excitation functions of dissipative heavy-ion collisions. The Fourier analysis of excitation function oscillations is presented. It suggests that S-matrix spin and parity decoherence, damping of the coherent nuclear rotation and quantum chaos are sufficient conditions to explain the no...

The important advantage to the search for Time-Reversal invariance violation (TRIV) in neutron nuclei interactions is the possibility of an enhancement of T-violating observables by many orders of magnitude due to the complex nuclear structure (see, i.e. paper [1] and references therein). Moreover, the variety of nuclear systems to measure T-violating parameters provides assurance that a possib...

Recent high-precision measurements of atomic parity-nonconserving transitions between the 6S and 7S states of cesium allow for a determination of the weak nuclear charge with a precision of 1.3%, providing an improved test of the standard model at low energy. Implications for new physics are examined in terms of low energy effects on the weak charge, in particular contact interactions and scala...

The dominant one-loop radiative corrections to atomic wave functions, those associated with vacuum polarization in the nuclear Coulomb field, are evaluated for the 6s-7s parity-nonconserving transition amplitude in (133)Cs. These corrections increase the size of this amplitude by 0.4% and, correspondingly, increase the difference between the experimental value of the weak charge Q(W)((133)Cs) a...

Excited states in Ba were studied with the Ba( d, p)Ba reaction at 24.0MeV, with a polarized deuteron beam using the Munich magnetic spectrograph Q3D. Many unambiguous spin-parity assignments were made up to an excitation energy of 2.2MeV, which allow a detailed comparison with different theoretical calculations, such as the interacting boson-fermion model and the shell model. PACS. 21.10.-k Pr...
