# Angular condition for matrix elements of the electromagnetic deuteron current

Abstract:

The paper is devoted to investigation of Grach-Kondratyuk angular condition. The matrix element of the «plus» component of the electromagnetic current of the deuteron defines four independent functions. Whereas, the matrix element should be expressed in three of the deuteron form factors: the charge, magnetic and quadrupole. This means that there must be additional equation. This equation is called the angular condition. The paper investigates the behavior of this condition as a function of the square of the momentum transfer, and shows its violation.
