【正】 The elastic scattering of 162 MeV л± from <sup>13</sup>C and the excitation function of <sup>13</sup>C(л<sup>+</sup>,л<sup>0</sup>)<sup>13</sup>N are analyzed in the frame of the Glauber theory.The nuclear wave function is assumedto be constructed by a valence nucleon plus a core of <sup>12</sup>C which is described by an independent αcluster model.A good agreement between the theory and experiment is obtained.
