Parity mixed doublets in A=36 nuclei.

چکیده
The γ-circular polarizations (Pγ) and asymmetries (Aγ) of the parity forbidden M1 + E2 γ-decays: 36Cl∗(Jπ = 2;T = 1;Ex = 1.95 MeV) → 36Cl(Jπ = 2+;T = 1; g.s.) and 36Ar∗(Jπ = 2;T = 0;Ex = 4.97 MeV) → 36Ar∗(Jπ = 2+;T = 0;Ex = 1.97 MeV) are investigated theoretically. We use the recently proposed Warburton-Becker-Brown shell-model interaction. For the weak forces we discuss comparatively different weak interaction models based on different assumptions for evaluating the weak meson-hadron coupling constants. The results determine a range of Pγ values from which we find the most probable values: Pγ = 1.1 · 10 −4 for 36Cl and Pγ = 3.5 · 10 −4 for 36Ar. PACS numbers: 21.60.Cs, 24.80.-x, 27.30.+t, 12.15.Ji

Collective T- and P-odd electromagnetic moments in nuclei with octupole deformations.
Parity and time invariance violating forces produce collective Pand Todd moments in nuclei with static octupole deformation. Collective Schiff moment, electric octupole and dipole and also magnetic quadrupole appear due to the mixing of rotational levels of opposite parity and can exceed singleparticle moments by more than a factor of 100. This enhancement is due to two factors, the collective ...
متن کاملPossible Interference Phenomena between Parity Doublets
Possible interference phenomena between parity doublets are discussed. In particular, the decay particle distributions of Z+ and A' produced in E +p capture and in x +p collision are analyzed. These distributions may have interference terms with odd parity. Experimental detection of such terms would constitute an unambiguous proof of the existence of parity doublets. It is further pointed out t...
متن کاملRelativistic Pseudospin Symmetry as a Supersymmetric Pattern in Nuclei
The doublet structure (for n ≥ 1) is expressed in terms of a “pseudo” orbital angular momentum l̃ = l + 1 and “pseudo” spin, s̃ = 1/2, coupled to j = l̃ − 1/2 and j = l̃ + 1/2. For example, [ns1/2, (n − 1) d3/2] will have l̃ = 1, etc. The states in Eq. (1) involve only normal-parity shellmodel orbitals. The states (n = 0, l, j = l + 1/2), with aligned spin and no nodes, are not part of a doublet. Th...
متن کاملAutomatically R-conserving supersymmetric SO(10) models and mixed light Higgs doublets.
In automatic R-parity conserving supersymmetric (SUSY) SO(10) models, the simplest way to accomodate realistic fermion masses is to demand that the light Higgs doublets are linear combinations of the {10} and {126} grand unified Higgs representations. We study the realization of this mixed light Higgs property ( MLHP ) consistent with doublet-triplet splitting in a minimal R-conserving SUSY SO(...
متن کاملDo parity doublets in the baryon spectrum reflect restoration of chiral symmetry ?
We discuss the mass spectrum of highly-excited nucleon and ∆ * resonances. The spectrum exhibits parity doublets, pairs of resonances of identical total angular momentum J but of opposite parity. It has been proposed that the parity doublets evidence restoration of chiral symmetry at large baryon excitation energies. We compare this conjecture with the possibility that high-mass states are orga...
