Two-nucleon parity nonconserving (PNC) interaction induced by the singleparticle PNC weak potential and the two-nucleon residual strong interaction is considered. An approximate analytical formula for this Induced PNC Interaction (IPNCI) between proton and neutron is derived (Q(rσp × σn)δ(rp − rn)), and the interaction constant is estimated. As a result of coherent contributions from the nucleo...

Chirality of Tensors and Parity-Nonconserving Interactions

T) = 2.4 +0.4 DAYS electrostatic interaction between Sf and 6d electrons removes the degeneracy in the total angular momentum. Thus under this approximation the ground-state wave function is ('Ds/s I4) ti/s giving a g value of 0.6547 if diamagnetic corrections and the relativistic breakdown of Russell-Saunders coupling are neglected. The authors wish to acknowledge their indebtedness to J. L. W...

Nuclear Anapole Moments and the Parity-nonconserving Nuclear Interaction

The anapole moment is a parity-odd and time-reversal-even electromagnetic moment. Although it was conjectured shortly after the discovery of parity nonconservation, its existence has not been confirmed until recently in heavy nuclear systems, which are known to be the suitable laboratories because of the manybody enhancement. By carefully identifying the nuclear-spin-dependent atomic parity non...

Parity Nonconserving Current in Conductors of Electricity

The effects due to the weak interaction between the conduction electrons and the lattice nuclei in external magnetic field are considered. It is shown that the continuous current arises under the influence of the rotating magnetic field.
