Negative Pions from Neutron Bombardment of Deuterons
Abstract
In order to obtain information on the neutron-neutron interaction, a cloud chamber filled with deuterium gas was bombarded with the neutron beam of the Berkeley 184-inch synchrocyclotron. The spectrum of the neutron beam, which is produced by 340-Mev protons on a 2.5-inch lithium deuteride target, is peaked at 300 Mev and extends to 340 Mev. The three reactions d(n, π-p)d, d(n, π-pn)p, and d(n, π-)He3 were studied. A total of 310 events were examined; the three reactions contributed 208, 80, and 22 events respectively. Laboratory-system angular distributions and energy spectra of the mesons are presented. Comparisons were theory indicate agreement with the predictions of the charge-independence hypothesis.
