Reaction Cross Sections

We study theoretically pion double charge exchange reactions leading to double pionic atoms. The reaction cross-sections with two pions in the deeper bound pionic orbits in 208Pb are calculated with realistic pionic atom wave functions and distortion effects. The cross-sections are found to be d2σ/dEdΩ~10−3−10−4 µ b/srMeV , which are only a small fraction of the double charge exchange background.

Measured Strength

Studying the weak nuclear response, especially the Gamow-Teller (GT) transitions, of stable as well as unstable pf-shell nuclei, is one of the key issues in nuclear and astro-nuclear physics. We study the decay half-lives and the GT transitions starting from Tz = ±1 and ±2 mirror nuclei, respectively, by means of β decays and complementary hadronic (3 He , t) charge-exchange reactions. Under the assumption that isospin is a good quantum number, symmetry is expected for mirror nuclei and the GT transitions starting from the mirror nuclei. The half-lives and branching ratios and the measured strength distributions of GT transitions are compared and also combined for the understanding of the nuclear structure of pf-shell nuclei far-from-stability.

This is a report on some preliminary results of an experiment (Calvelli et al. 1964; Bordner et al. 1965; Bulos et al. 1964 a, b ) performed at the Cosmotron to measure the total cross sections and the angular distributions in the charge exchange reaction π - + p → π 0 + n at eleven energies between 500 and 1150 MeV. The experiment was accomplished by a collaboration between groups of Brandeis, Brown and Harvard Universities and the Massachusetts Institute of Technology in U.S.A. and of Padua University in Italy.
