First charge-exchange measurements with SHARAQ

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution

Abstract

The isovector spin monopole resonances (IVSMR) of the β⁺ type were observed for the first time in the ²⁰⁸Pb and ⁹⁰Zr(t,³He) reactions at 300 MeV/u. The experiment was performed at the RI Beam Factory (RIBF) at RIKEN by using the newly-constructed magnetic spectrometer SHARAQ. The double differential cross sections for the ²⁰⁸Pb and ⁹⁰Zr(t,³He) reactions were obtained at the excitation energy of 0≤E_x≤70MeV and the scattering angles of 0°≤θ≤3°. The monopole component was identified by making a difference between the zero-degree and backward-angle spectra. The signatures of the IVSMR are observed at an excitation energy of 12 MeV(20 MeV) in ²⁰⁸Pb(⁹⁰Zr)(t,³He) reaction, which agrees fairly well with the theoretical predictions.
