Description

A new model for short-range isoscalar current in the deuteron and NN system is developed and tested on a variety of isoscalar magnetic observables such as the deuteron magnetic moment, magnetic form factor, and the circular polarization of γ quanta at n-vectorp radiative capture at thermal neutron energies. The model for electromagnetic two-nucleon current proposed is based on generation of an intermediate dibaryon in the short-range NN interaction

Abstract (Russian)

Новая модель короткодействующего изоскалярного тока в дейтроне и NN-системе развита и протестирована на различных изоскалярных магнитных наблюдаемых, таких, как магнитный момент дейтрона, магнитный формфактор и циркулярная поляризация γ-квантов в радиационном захвате тепловых нейтронов n-vectorp → dγ-vector. Модель электромагнитного двухнуклонного тока, предложенная в работе, основана на образовании промежуточного дибариона в процессе NN-взаимодействия на малых расстояниях
