Limints on a nucleon-nucleon monopole-dipole (axionlike) P,T-noninvariant interaction from spin relaxation of polarized He
نویسنده
چکیده
A new limit is presented on the axionlike monopole-dipole coupling in a range 10 − 1 cm. The gradient of spin-dependent nucleon-nucleon potential between He nucleus and nucleons of the walls of the cell containing He should affect the spin relaxation rate. The limit is obtained from existing data on the relaxation rate of spin-polarized He. PACS: 14.80.Mz; 12.20.Fv; 29.90.+r; 33.25.+k

Optical-model description of time-reversal violation in neutron-nucleus scattering.
A time-reversal-violating spin-correlation coefficient in the total cross section for polarized neutrons incident on a tensor rank-2 polarized target is calculated by assuming a time-reversal-noninvariant, parity-conserving “five-fold” interaction in the neutron-nucleus optical potential. Results are presented for the system n + Ho for neutron incident energies covering the range 1–20 MeV. From...

A possible resolution to the question of where the nucleon gets some portion of its internal angular momentum, not carried by the valence quarks, is given in terms of the electromagnetic field angular momentum of the nucleon. This field angular momentum is similiar in origin to that of the Thomson dipole (an electric charge and a magnetic monopole), but arises from the interaction of the quark ...

Using only the current empirical information on the nucleon electromagnetic form factors we map out the transverse charge density in proton and neutron as viewed from a light front moving towards a transversely polarized nucleon. These charge densities are characterized by a dipole pattern, in addition to the monopole field corresponding with the unpolarized density. Furthermore, we use the lat...

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...
