Research Abstract

We proposed a new probe, a parity-transfer (^<16>O,^<16>F) reaction for the study of 0^- states, whose distributions are expected to reflect pion-like correlations in nuclei. The accomplishments of this research are; firstly, we planed the ^<12>C(^<16>O,^<16>F) experiment at 250A MeV in order to confirm the effectiveness of the parity-transfer reaction. Second, we developed a new proton detector system for the (^<16>O,^<16>F) experiment. Thirdly, we analyzed the parity-transfer (^<16>O,^<16>F) reaction at 250A MeV using the distorted wave Born approximation and found that the distortion effect is important to understand its angular distribution quantitatively.
