Model Formalism

Cross sections for the reaction 14N(π+,π0)14O are calculated near the (3, 3) resonance using the impulse approximation together with the Chew–Low amplitude in the framework of a two-hole shell model formalism. Various sets of wave functions are used and comparisons are made with existing experimental data and other theoretical calculations.

Charge-exchange cross-sections have been measured for ions of between 25 and 900 eV energy in collision with neutral atoms. The method involves collection and measurement of the chargeexchange ions when a beam is passed through gas. The cases A + in A, He + in He are in satisfactory agreement with the measurements of Rostagni, although showing no maxima at low energies. The cases O+ in N 2 , O + in A, and N + in A show abnormally high values which are believed to be due to the presence of m etastable ions, as well as contributions from the nitrogen rotational and vibrational energy. The cases H + in A, in Kr, in Xe and C + in Xe rise with an increasing energy, to a maximum when a Δ E /hv ≏ 1, Δ E being the energy defect of the hv process, v the velocity of the incident ion, and a a parameter of atomic dimensions ~ (5 to 10) 10 -8 cm.

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.

Results based on an analysis of 25% of the pictures obtained from a measurement of the charge-exchange reaction π - p → n 0 n with thick-plate spark chambers are given. Differential and total cross sections for charge-exchange scattering were obtained at five momenta centred about the T = 1/2 resonance found at 2.07 GeV/ c in the π - p total cross section. In the vicinity of the resonance the total cross section is falling smoothly, and the higher coefficients of Legendre polynomial expansions show no significant variation with momentum. From this it is concluded that there is either a complicated interference of several states at the resonance or that the resonance is in a relatively high partial wave and is mainly inelastic.
