We propose a novel method for analysis of experimental data obtained in relativistic nucleus—nucleus collisions. The method,
based on the ideas of random matrix theory, is applied to detect systematic errors that occur in measurements of momentum
distributions of emitted particles. The unfolded momentum distribution is well described by the Gaussian orthogonal ensemble
of random matrices, when the uncertainty in the momentum distribution is maximal. The method is free from unwanted background
contributions.

An analysis of quasiparticle correlations with special emphasis on transition matrix elements have been done for a self-consistent
cranking model. It is pointed out that a second order of the boson representation of a transition operator leads to a signature
dependence of transition probabilities between excited one-phonon states in even-even nuclei. Moreover, it brings about the
new contribution to an expectation value of electromagnetic moments in the yrast line states of deformed nuclei. 相似文献

In this paper it is shown that the projective cover of the trivial irreducible module of a finite-dimensional solvable restricted Lie algebra is induced from the one dimensional trivial module of a maximal torus. As a consequence, the number of the isomorphism classes of irreducible modules with a fixed p-character for a finite-dimensional solvable restricted Lie algebra L is bounded above by p MT(L), where MT(L) denotes the maximal dimension of a torus in L. Finally, it is proved that in characteristic p > 3 the projective cover of the trivial irreducible L-module is induced from the one-dimensional trivial module of a torus of maximal dimension, only if L is solvable. 相似文献

Manifestations of pronounced shell effects are discovered when non-axial octupole deformations are added to a harmonic oscillator
model. The degeneracies of the quantum spectra are in good agreement with the corresponding main periodic orbits and winding
number ratios which are found by classical analysis.

The General Relativity formulated with the aid of the spin connection coefficients is considered in the finite space geometry of similarity with the Dirac scalar dilaton. We show that the redshift evolution of the General Relativity describes the vacuum creation of the matter in the empty Universe at the electroweak epoch and the dilaton vacuum energy plays a role of the dark energy. 相似文献

Dual-detector differential non-destructive Fourier transform detection in a quadrupole ion trap is shown to improve signal intensity and reduce noise compared with spectra recorded using a single detector. A larger area detector in each end-cap electrode is machined to fit its hyperbolic shape and so minimize field imperfections on the z-axis. Argon, acetophenone and bromobenzene spectra were recorded to allow a comparison between single- and dual-detector (differential) modes of detection and to demonstrate the improvement achieved with differential detection.
