2. (5 pts) Nucleon resonances with spin 3/2 include the A(1232) (with charge states ++, +, 0, and ), plus similar higher energy resonances, A0600), A0700) and A(1920). In each case, the number in parentheses indicates the resonance mass (or rest energy) in MeV. When pions of energy E scatter from nucleons in a target at rest in the lab frame, these resonacnes can be produced, e.g., 7r + N > A0232). Each resonance appears as a peak in the total scattering cross-section plotted as a function of the (lab frame) pion energy E. At what energies E do these resonances appear
