The reactions e +e - → π +π - and e +e - → N̄N with N = p, n are studied in a nonperturbative quark model. The work suggests that the two-step process, in which the primary q̄q pair first forms a vector meson which in turn decays into a hadron pair, is dominant over the one-step process in which the primary q̄q pair is directly dressed by additional q̄q pairs to form a hadron pair. To reproduce the experimental data of the reaction e +e - → n̄n and p̄p, a D-wave, ω-like vector meson with a mass of around 2 GeV has to be introduced.
