Pionic modes of excitation in continuum from the (p, n) reaction Academic Article uri icon

abstract

  • The continuum spectra of the 90Zr(p, n) reaction at Ep = 200 MeV are studied in the DWBA up to high excitation h {combining short stroke overlay}(60 MeV) and large momentum transfer q(3omega). The response function is obtained in a local-density approximation, taking into account p-h and -h excitation and the short-range correlation g between them. For small g 0.5, a broad bump due to the opalescence effect can be seen in the calculated cross section at rather low excitation and near q 2.2omega. However, for larger g, this effect is suppressed, and a broader bump in cross section is located at higher excitation. 1982.
