The coherent production of pi and rho mesons in nusub mu(bar nusub mu)--neon charged-current interactions has been studied using the Fermilab 15-foot bubble chamber filled with a heavy Ne-Hsub 2 mix and exposed to the Teva- tron quadrupole triplet (anti)neutrino beam. The nusub mu (bar nusub mu) beam had an average energy of 80 GeV (70 GeV). From a sample corresponding to approximately 28 000 charged-current interactions, net signals of (53plus minus9) musup plus minuspisup minus plus coherent events and (19plus minus7) musup plus minuspisup minus pluspisup 0 coherent events are extracted. For ital Egt10 GeV, the coherent pion production cross section is determined to be (3.2plus minus0.7)times10sup minus38 cmsup 2 per neon nucleus whereas the coherent rho production cross section is (2.1plus minus0.8)times10sup minus38 cmsup 2 per neon nucleus. These cross sections and the kinematical characteristics of the coherent events at vert barital tvert barlt0.1 GeVsup 2 are found to be in general agreement with the predictions of a model based on the hadron dominance and, in the pion case, on the partially conserved axial-vector current hypothesis. Also discussed is the coherent production of systems consisting of three pions.
