Inclusive pion double charge exchange on 16O at 0.6-1.1 GeV
2003
The inclusive pion double charge exchange (DCX) on oxygen nuclei has been measured in the region where additional pion production is kinematically forbidden. The experiment was performed at ITEP PS at incident pi- kinetic energies T_0= 0.59, 0.75 and 1.1 GeV. The integrated forward differential cross section was found to decrease with energy slowly. At 1.1 GeV it exceeds the theoretical prediction within the conventional sequential single charge exchange mechanism with a neutral pion in the intermediate state (Glauber elastic rescattering) by about half an order of magnitude. The sequential mechanism with two pions in the intermediate state (Glauber inelastic rescatterings), which was propo…
Measurement of magnetic monopole transition in electron scattering fromO16as direct test of dispersive effects
1991
For the first time an experiment has been performed to measure a magnetic monopole transition in inelastic electron scattering. In {sup 16}O the 0{sup +}{r arrow}0{sup {minus}} transition to the level at {ital E}{sub {ital x}}=10.957 MeV has been observed with a cross section of {ital d}{sigma}/{ital d}{Omega}=(5.4{plus minus}3.8){times}10{sup {minus}37} cm{sup {minus}2}/sr. Measurement of this transition is a direct signature of two-step contributions in electron scattering. Our measurement is in good agreement with the strength calculated for this transition.
