    "abstract": "In this updated and expanded version of our delayed Comment we show that the\nnp backward cross section, as presented by the Uppsala group, is seriously\nflawed (more than 25 sd.). The main reason is the incorrect normalization of\nthe data. We show also that their extrapolation method, used to determine the\ncharged piNN coupling constant, is a factor of about 10 less accurate than\nclaimed by Ericson et al. The large extrapolation error makes the determination\nof the coupling constant by the Uppsala group totally uninteresting.",
