Measurement of the x0 cross-sections in pi- p interactions at 1.6 gev/c (x0 ---> neutrals)/(x0 ---> total)

Basile, M. ; Bollini, D. ; Dalpiaz, P. ; et al.
Nuovo Cim.A 3 (1971) 371-384, 1971.
Inspire Record 71622 DOI 10.17182/hepdata.37600

The reactions π−p→ n+(X0→total) and π−p→ n+(X0→neutrals) have been studied at 1.6 GeV/c with the Bologna-CERN neutron missing-mass spectrometer. Both reactions have been detected without the use of visual techniques. The results are: σ(X0→total)=(108±14) μb and σ(X0→neutrals)=(20.0±3.5) μb, giving a branching ratio Γ(X0→neutrals)/Γ(X0→total)=(18.5±2.2)%. The branching ratio for other possible, so far undetected, neutral decay modes of the X0 turns out to be (2.4±1.9)%.

Further evidence for the decay mode x(0) ---> gamma gamma and determination of the branching ratio x(0) ---> gamma gamma/ x(0) ---> total

Basile, M. ; Bollini, D. ; Dalpiaz, P. ; et al.

Inspire Record 68511 DOI 10.17182/hepdata.33085

41 ± 8 events of the type X 0 → γγ have been observed in a study of the reaction π − p → n(X 0 → γγ ) at 1.6 GeV/ c incident π -momentum. This provides further evidence to our previous observation of this new X 0 decay mode and allows the determination of the branching ratio Γ(X 0 →γγ) Γ(X 0 → total =(1.7 ± 0.4)%. The theoretical implications of this result are discussed.

Pi- photoproduction from deuterium at laboratory energies 600 to 1250 mev

Scheffler, P.E. ; Walden, P.L. ;
Phys.Rev.Lett. 24 (1970) 952-954, 1970.
Inspire Record 62962 DOI 10.17182/hepdata.32219

The differential cross section for the reaction γ+n→π−+p was measured for laboratory photon energies between 600 and 1250 MeV, using a liquid deuterium target. The internal nucleon momentum distribution of the deuteron was used to calculate the major effect of using deuterium as a neutron target. The data show that the amplitude to excite the F15(1688) resonance is small, in agreement with a recent quark-model prediction.
