RCNP polarized (3)He ion source.

We have developed a polarized (3)He ion source named "SEPIS" (spin-exchange polarized ion source) at RCNP, and Department of Physics, Osaka Univeristy. The SEPIS uses a large spin-exchange cross section, sigma(se), and a small electron capture cross section,sigma(ec), for the (3)He(+)+Rb system theoretically expected at low (3)He(+) incident energies. The validity of SEPIS was experimentally proven by observing the (3)He(+) nuclear polarization as a function of the incident (3)He(+) energy.
