The cross sections for the reaction (3He, t) at the proton and at the I2C nucleus, accompanied by the excitation of A isobars in the target, have been measured at high energies for the first time. The statistical error is S5%, and the normalization error is S 10%. The mechanisms of importance to the production of the isobar in the nucleus in this reaction do not reduce to the production of this isobar at one of the nucleons of the nucleus.
