| Zusammenfassung: | A polarized 3He system is being developed for an experiment on time-reversal invariance in nuclear reactions.
Spin-exchange optical pumping is employed to polarize the 3He nuclei.
A quartz glass cell and a sapphire cell are used as containers for the 3He. With the pulsed neutron beam at High Energy Accelerator Research Organization (KEK),
the polarizations of 3He were measured
for the quartz glass cell and the sapphire cell at a 3He pressure of 3 atm by employing a frequencynarrowing technique based on an external-cavity and were found to be 0.538 ± 0.004stat ± 0.02sys and 0.627 ± 0.002stat ± 0.01sys, respectively. KCI Citation Count: 2 |
