A Large Solid Angle Study of Pion Absorption on He3

The LADS collaboration Alteholz, T. ; Androic, D. ; Backenstoss, G. ; et al.
Phys.Rev.Lett. 73 (1994) 1336-1339, 1994.
Inspire Record 372679 DOI 10.17182/hepdata.19679

Measurements have been made of pi+ absorption on He3 at T_pi+ = 118, 162, and 239 MeV using the Large Acceptance Detector System (LADS). The nearly 4pi solid angle coverage of this detector minimizes uncertainties associated with extrapolations over unmeasured regions of phase space. The total absorption cross section is reported. In addition, the total cross section is divided into components in which only two or all three nucleons play a significant role in the process. These are the first direct measurements of the total and three nucleon absorption cross sections.

Proton polarization from pi+ absorption in He-3

MayTal-Beck, S. ; Aclander, Jaime L.S. ; Altman, A. ; et al.
Phys.Rev.Lett. 68 (1992) 3012-3015, 1992.
Inspire Record 339565 DOI 10.17182/hepdata.19868

We present the first polarization measurements for pion absorption on a nucleus heavier than the deuteron. The polarization of protons resulting from π+ absorption in the He3 was measured at bombarding energies of 120 and 250 MeV. Protons from absorption in a quasideuteron were selected by applying kinematical constraints. A significant discrepancy was observed between the experimental results and theoretical predictions. At 120 MeV the measured polarizations for He3 are consistent with those of the deuteron. At 250 MeV the angular distribution of the polarization is significantly different than for the deuteron, showing sensitivity to the nuclear density, and thus may be sensitive to short range correlations between nucleons.

MEASUREMENT OF THE DIFFERENTIAL CROSS-SECTION FOR THE REACTION PI+ D ---> P P AT MOMENTA BETWEEN 0.48-GEV/C AND 1.16-GEV/C

Akemoto, M. ; Baba, K. ; Endo, I. ; et al.
Phys.Lett.B 149 (1984) 321-324, 1984.
Inspire Record 210255 DOI 10.17182/hepdata.30477

The differential cross section for the reaction π + + d → p + p has been measured at pion momenta between 0.48 and 1.16 GeV c with steps of 20 and 40 GeV c for seven CM proton angles between 6° and 61°. At smaller angles, the measured cross sections show a dip at around 0.7 GeV c , while at larger angles the cross sections vary monotonically as a function of incident momentum. The angular distribution shows a considerably rapid variation with increasing momentum. Legendre polynomial fits of the data are presented.
