Abstract

We have constructed a new type of spin polarized solid proton target which can be operated under a low magnetic field of 0.08T and a high temperature of 100K. We have measured for the first time the polarization asymmetry of an unstable beam of ⁶He at an energy of 71MeV/u. Optical potential analyses have been carried out.
