The parity-transfer $({}^{16}{\rm O},{}^{16}{\rm F}(0^-,{\rm gs})) $ reaction is presented as a
new probe for investigating isovector $0^-$ states in nuclei. The properties of $0^-$ states
provide a stringent test of the threshold density for pion condensation in nuclear matter.
Utilizing a $0^+\rightarrow 0^-$ transition in the projectile, the parity-transfer reaction
transfers an internal parity to a target nucleus, resulting in a unique sensitivity to unnatural-
parity states. Consequently, the selectivity for $0^-$ states is higher than in other reactions …

The parity-transfer reaction is presented as a new probe for investigating isovector states in nuclei. The properties of states provide a stringent test of the threshold density for pion condensation in nuclear matter. Utilizing a transition in the projectile, the parity-transfer reaction transfers an internal parity to a target nucleus, resulting in a unique sensitivity to unnatural-parity states. Consequently, the selectivity for states is higher than in other reactions employed to date. The probe was applied to a study of the states in via the reaction at . The excitation energy spectra were deduced by detecting the pair produced in the decay of the ejectile. A known state at was observed with an unprecedentedly high signal-to-noise ratio. The data also revealed new candidates of states at and . The results demonstrate the high efficiency of state detection by the parity-transfer reaction.
