POLARIZATION OF D-D NEUTRONS FOR DEUTERON ENERGIES FROM 1.9 TO 11 MEV
Technical Report
·
OSTI ID:4037921
The polarization of neutrons produced in the D(d,n)He/sup 3/ reaction was measured from 1.9 to 11 Mev by employing the technique of rotating the polarization vector with a magnetic field, the neutron detectors remaining fixed. Helium, contained under high pressure in a thin-walled cell, served as the analyzer. The background counts were reduced by observing coincidences between the helium recoils and the scattered neutrons. The polarization at 45 deg c.m. reaction angle was found to vary monotonically from -- 0.12 plus or minus 0.02 at 1.9 Mev to + 0.30 plus or minus 0.05 at 11 Mev, changing sign at about 4.2 Mev. At several energies angular distributions of the polarization were measured. (auth)
