چکیده

Recent results in parity nonconserving neutron-nucleus scattering show a tendency for the parity nonconserving effects to predominantly have the same sign. Explanations of this phenomenon all require a weak matrix element between single-particle levels in heavy nuclei to be ~100 eV. This paper contains a discussion of this effect and how the same phenomenon will manifest itself in other systems. The gamma decay of Pb is given as an example of a system where the weak matrix element between single-particle levels in a heavy nucleus can be measured directly.

Evaluation of the mean intensity of the P–odd mixing of nuclear compound states

A temperature version of the shell-optical-model approach for describing the lowenergy compound-to-compound transitions induced by external single-particle fields is given. The approach is applied to evaluate the mean intensity of the P-odd mixing of nuclear compound states. Unified description for the mixing and electromagnetic transitions allows one to evaluate the mean intensity without the ...

Role of estuarine natural flocculation process in removal of Cu, Mn, Ni, Pb and Zn

The flocculation of dissolved heavy metals is a process which has an important effect on decreasing the concentration of the colloidal elements during estuarine mixing of river water and sea or ocean water. During this important process, a large amount of colloidal elements change into particles in the form of flock and the dissolved loads decline. This study is performed to evaluate the mechani...

Classical Fields and Heavy Ion Collisions

To understand what is happening in relativistic heavy ion colliders, currently RHIC in Brookhaven and in the future the LHC at CERN, one needs to understand not only hard probes, but also bulk particle production and thermalisation. It can be argued that the large phase space densities of partons in the small-x wavefunction of the nuclei generate a hard enough momentum scale to allow weak coupl...

We consider the Parity Nonconserving (PNC) mixing in the ground state of exotic (halo) nuclei caused by the PNC weak interaction between outer neutron and nucleons within nuclear interior. For the nucleus 11 Be as an example of typical nucleus with neutron halo, we use analytical model for the external neutron wave functions to estimate the scale of the PNC mixing. The amplitude of the PNC mixi...
