PURPOSE:To detect the excitation of resonance and the detection of two nuclides independently by arranging two coils on a cylindrical surface parallel with the axis of a sample tube diagonally while crossing each other at the right angle while a third coil is arranged on the axis intersecting said two coils at the right angle. CONSTITUTION:A first detection coil is arranged on the outer surface of a first glass cylinder coaxially arranged in the perimeter of a sample tube with the axis thereof parallel to the direction of the electrostatic field in such a manner that the coil surface is at 45 deg. to the axis of the cylinder. A second detection is arranged on the inner surface of a second glass cylinder arranged coaxially in concentric circle with the first glass cylinder in such a manner as to have the coil surface thereof intersection the first detection coil at the right angle. A third coil is arranged in such a direction that it crosses the first and second detection coils cross at the right angle and used for an exciting coil. This eliminates interaction between three coils thereby permitting the excitation of the resonance and the detection of two unclides independently. |
