Inelastic Interactions Between 6.8-BeV/c $\pi^-$ Mesons and Nucleons

Birger, N.G. ; Wang, Kangchang ; Trka,Z. ; et al.
Sov.Phys.JETP 14 (1962) 1043-1052, 1962.
Inspire Record 1387796 DOI 10.17182/hepdata.17077

An analysis was made of 355 interactions between 1r- mesons and nucleons. The momentum and angular distributions of the secondary charged particles were measured. Information on 1r0 mesons produced in the interactions has been obtained. The experimental data are compared with the statistical theory. The results suggest that peripheral interactions may exist. In events of low multiplicity (two-prong cases) "one-meson" peripheral interactions play an important role, while in events of large multiplicity an important role is played by interactions not of the one-meson type, among which also central collisions are possible.

LARGE ANGLE pi- p ELASTIC SCATTERING AT 3.63-GeV/c.

Perl, Martin L. ; Lee, Yong Yung ; Marquit, Erwin ;

Inspire Record 98 DOI 10.17182/hepdata.26685

The differential cross section for elastic scattering of 3.63−GeVc π− mesons on protons was studied with a hydrogen bubble chamber, the emphasis being on large-angle scattering. From 90 to 180° in the barycentric system, the cross section is roughly flat with an average value of 2.7±1.0 μb/sr. Near and at 180°, there may be a slight peak of magnitude 10±6 μb/sr. But if such a peak exists, it is only one-third to one-fourth the size of the 180° peak found in 4.0 GeVc π++p elastic scattering. In addition to comparison with other π−+p and π++p large-angle elastic-scattering measurements, this measurement is compared with large-angle p+p elastic scattering. In the forward hemisphere a small peak or a plateau exists at cos θ*=+0.60. This appears to be a second diffraction maximum such as has been found in lower-energy π+p elastic scattering. A survey of indications of such a second diffraction maximum in other π+p measurements shows that it always occurs in the vicinity of −t=1.2 (GeVc)2, where t is the square of the four-momentum transfer. As the incident momentum increases, the relative size of this second maximum decreases.

Properties of $\pi^0$ Mesons Produced with Strange Particles in $\pi^- - p$ and $\pi^- - C$ Interactions

Belyakov, V.A. ; Wang, Yung-Ch'ang ; Viryasov, N.M. ; et al.
Sov.Phys.JETP 17 (1963) 991-995, 1963.
Inspire Record 1387688 DOI 10.17182/hepdata.70201

This investigation was performed with a 24-liter propane bubble chamber [i] and is a continu- ation of our previous work on the production of strange particles by 7-8-BeV 1r- mesons on hydrogen and carbon. [ 2 - 5 ] The properties of 1r 0 mesons inferred from the y quanta accom- panying A and K 0 production are given, and are compared with the properties of 1r+ and 7r- mesons emitted in A and K 0 production processes. The possibility of a resonance with radi- ative decay is noted.
