Abstract

Charge-exchange reactions at beam energies of āˆ¼100 MeV/u and above provide a powerful way to study isovector excitations and isovector giant resonances in particular. Macroscopically, isovector giant resonances are associated with out-of-phase oscillations of proton and neutron matter in nuclei. Microscopically, they are described as collective one-particle-one-hole (1pā€‰āˆ’ā€‰1h) excitations in which isospin is transferred. Therefore, the experimental study of the isovector giant resonances provides insight into the bulk properties of nuclear matter, as well as the microscopic structure of nuclei, with impactful applications in astrophysics and neutrino physics. This chapter focuses on the properties of charge-exchange reactions and isovector giant resonances, with an emphasis on the experimental and analysis tools used to identify and isolate specific isovector giant resonances and extract information about their key features. In addition, the motivation for studying the different isovector giant resonances will be discussed.
