A windowless tritium gas target has been built to produce 10 13 14 MeV nutrons/s. Gas escaping from the target chamber through the beam entrance apertures is recirculated in a closed system. A 10 torr pressure gradient is maintained between the targe

The performance of a compact and efficient neutron generator, using the 3H(d, n) reaction and a gas target, is reported. The target is formed in a windowless, differentially pumped vessel pressurised to 7.5 Torr. An extended source of 15 MeV neutrons

The asymmetry in the scattering of d-T neutrons from helium has been measured for incident deuteron energies between 6 and 11 MeV at various emission angles. Asymmetries greater than 0.35 were observed at 30° emission angle throughout the energy reg

Neutron polarization produced in the scattering of 1-MeV neutrons by deuterons has been measured. Asymmetry measurements were performed for c.m. scattering angles of 70°, 110° and 140° using the method of Levintov, Miller, and Shamshev. The polari

The polarization of neutrons scattered from deuterons has been measured for several angles at neutron energies of 1.9, 6.0, 10.0, 16.4 and 23.7 MeV. The polarization is less than 0.05 for neutron energies of 1.9 and 6.0 MeV and at 10.0 and 16.4 MeV p

Previous measurements in this laboratory on the polarization of the neutrons from the T(p, n)He3 reaction have been extended to lower energies and other emission angles. A solenoid was used to precess the spin vector of the neutrons and the polarizat

The polarization of 4.4 MeV neutrons scattered from 6Li and 7Li has been measured for centre-of-mass scattering angles between 46° and 126°. The angular dependence of polarization observed with both isotopes exhibits a dominant sin 2Θ dependence.
