Abstract: (APS)
The momentum spectra of He3 and H3 nuclei produced in p+d collisions have been measured with high resolution. Data were obtained at several angles and incident proton energies of about 745 MeV. Each spectrum exhibits a peak due to single pion production and a continuum due to double pion production. An anomalous bump has been observed in the He3 spectra which we interpret as an I=0 virtual di-pion with a scattering length of 2 ħ/μc. In this series of four papers we summarize the data obtained over a series of three cyclotron runs. The first paper deals with the experiment and techniques, and the second with the results of the measurements on single-pion production. Next we describe an experiment to determine the spin and parity of the anomalous bump, and finally we discuss its interpretation.References(5)
