N2 - In a reinvestigation of the nucleon-nucleon initiated isoscalar single-pion production we noted that the upper limits for the decay of the dibaryon resonance [Formula presented]into the isoscalar [Formula presented]channel via the routes [Formula presented]and [Formula presented]are a factor of two smaller than given in Ref. [1]. The reason is that the isoscalar single-pion production cross section [Formula presented]derived in Ref. [1] by the relation [1–3]: [Formula presented] is twice the isoscalar part of the pn-induced single-pion production cross section [Formula presented] i.e. [3]: [Formula presented] In Ref. [1] the quantity [Formula presented]has been plotted in Fig. 7. Based on this figure the upper limits for the hypothetical [Formula presented]decays were determined. However, the relevant cross section for the routes [Formula presented]and [Formula presented]is not [Formula presented] but [Formula presented] Hence the upper limits for these routes are a factor of two smaller than given in Ref. [1] leading thus to upper limits (90% C.L.) of 5% and 7%, respectively, for the branching ratios of the respective decays of [Formula presented] This result excludes [Formula presented]as major intermediate decay configuration and restricts a possible [Formula presented]configuration to less than 25% [4].
