N − d scattering including electromagnetic forces
نویسنده
چکیده
The electromagnetic potential consisting in the Coulomb plus the magnetic moment interactions between two nucleons is studied in nucleon-deuteron scattering. For states in which the relative N − d angular momentum L has low values the three–nucleon problem has been solved using the correlated hyperspherical harmonic expansion basis. For states in which the angular momentum L has large values, explicit formulae for the nucleon-deuteron magnetic moment interaction are derived and used to calculate the corresponding T -matrices in Born approximation. Then, the transition matrices describing N − d elastic scattering have been derived including an infinite number of partial waves as required by the 1/r3 behavior of the magnetic moment interaction. Appreciable effects are observed in the vector analyzing powers at low energies. The evolution of these effects by increasing the collision energy is examined.

متن کاملScattering Forces within a Left-Handed Photonic Crystal
Electromagnetic waves are known to exert optical forces on particles through radiation pressure. It was hypothesized previously that electromagnetic waves inside left-handed metamaterials produce negative radiation pressure. Here we numerically examine optical forces inside left-handed photonic crystals demonstrating negative refraction and reversed phase propagation. We demonstrate that even t...

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
