Simultaneous measurements of the reactions

“…For the charged exit channel, the older data seem to follow a steeper angular dependence than the present data. The cross sections from Källne et al [25] for the forward angles are smaller than the present ones. For the neutral exit channel there is a striking agreement between the present data and those of Cameron et al [9], but the data from Carroll et al [28] differ.…”

“…The uncertainty from the fit contains the systematical uncertainty resulting from background subtraction. [27,29,25] are from negative pion absorption on 3 He. The curves are model calculations [2] using the Bonn B potential (solid curve), Bonn A (dotted curve), and Paris interaction (dashed curve).…”

“…[10] are for the related nd → tπ 0 reaction. They [25][26][27] for the 3 H π + reaction (left part) and from [10,9,28] for the 3 He π 0 reaction (right part). 12 have extremely large error bars.…”

“…8 The total cross sections are compared in Fig. ' [25,18,27,[29][30][31] for the charged exit channel. In addition to the cases mentioned above, the data from Aniol et al [29] and Weber et al [27] were transformed using detailed balance.…”

“…The data from Ref. [25] and Ref. [27] are from pion absorption and are transformed assuming charge symmetry as well as time reversal invariance and hence these data were transformed using detailed balance.…”
