dc.description.abstract	We study the threshold production of two pions induced by neutrinos in nucleon targets. The contribution of nucleon, pion, and contact terms are calculated using a chiral Lagrangian. The contribution of the Roper resonance, neglected in earlier studies, has also been taken into account. The numerical results for the cross sections are presented and compared with the available experimental data. It has been found that in the two-pion channels with pi(+)pi(-) and pi(0)pi(0) in the final state, the contribution of the N* (1440) is quite important and could be used to determine the N* (1440) electroweak transition form factors if experimental data with better statistics become available in the future.
