A Large Solid Angle Study of Pion Absorption on He3
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.Comment: 8 pages, LaTeX. 3 figures, anonymous ftp MITLNS.MIT.EDU, cd LADS.
