Angelescu, A. Mihul, L. Pascu, T. Preda, I. Lazanu, R. Ionica, R. Garfagnini, G. Piragino, V. Lyashenko, I. Falomkin, Yu. Shcherbakov] Поглощение пионов в3He при энергиях 100, 120 и 145 МэВ Summary: π+ true absorption cross-section on3He has been measured at 100, 120, and 145 MeV. The maximal total cross-section values of the reaction π+3He→ppp turn out to be 10, 16, and 19 mb, respectively. About 16% of the cross-section corresponds to three-nucleon absorption. The measured angular distribution as a function of the opening angle between the two fast protons has been fitted with the Legendre polynomial expansionA 0+A2P2(cos θ). The values of the coefficients turn out to beA 0=(1.7±0.5) mb/sr, andA 2=(1.4±0.5) mb/sr, in agreement with the values obtained in the study of the pion absorption on deuteron.
