Abstract

A source for nuclear polarized lithium-6 and -7 ions was built following the method of separation of the atomic hyperfine states in a strong inhomogeneous magnetic sextupole field and ionisation of the selected atoms by electron bombardment in a weak homogeneous field. The velocity distribution of the atomic beam formed by a Laval nozzle and the focussing properties of the sextupole magnet were determined using a mechanical velocity selector. After separation of the two isotopes the ion beam has an intensity of 10−9 ampere. As no background of unpolarized lithium ions was found, a vector polarisation of (32±1)% and (24±1)% for lithium-6 and -7 and a tensor polarisation of (−32±1)% for lithium-6 can be expected.
