摘要：
A 130 MeV primary tritium beam, newly developed at the superconducting cyclotron AGOR, has been used for the investigation of 1 hw and 2 hw isovector giant resonances in Co-58 via the r(+) channel. The angular distributions of double-differential cross sections have been extracted between E-x and 30 MeV from theta(lab) = 0degrees to 6degrees. A DWBA analysis have been extracted between E. with normal-mode (NM) wave functions and a multipole-decomposition analysis (MDA) indicate strength for the monopole resonances (dominated by the spin-flip transition) fragmented between 10 and 27 MeV excitation energy, in rather good agreement with preliminary RPA calculations.
