[en] Full text: Investigation of nuclear reactions is the basic source of obtaining of the information about structure of nucleus, its properties and mechanisms of nuclear interaction. The most convenient mean of obtaining such information is investigation of direct reactions which occurs in the peripheral part of a nucleus. There are plenty of works on studying the direct reactions on the boron isotopes, but it should be said that they were mainly carried out at the energies 8 /18 MeV. We have obtained the experimental values of differential cross sections of the reaction (d,t) on the ¹⁰B and ¹¹B isotopes at the energy E_d=25 MeV within the angular region 7^o - 97^o with step 2^o on the isochronous cyclotron U-150-M of Institute of Nuclear Physics NNC of Kazakhstan. The statistics in the peaks corresponding to population of the ground states of nuclei ⁹B and ¹⁰B in the reactions ¹⁰B(d,t)⁹B and ¹¹B(d,t)¹⁰B is 200-300 events. The (δE-E) - technique was used in the experiments for selection of the reaction products. The analysis of these processes has been carried out using the modified Distorted Wave Born Approximation which includes formalism of the distorted wave method dispersion approaches of the Direct Reaction Theory [1, 2]. For calculation of the distorted waves the optical potentials of interaction in the systems d+¹⁰B and d+¹¹B have been used which were obtained from the analysis of deuterons elastic scattering by nuclei ¹⁰B and ¹¹B in the energy interval 12 / 28 MeV within the framework of the optical model. The asymptotical normalization coefficients of the overlapping functions as well as the spectroscopic factors for the configurations (n+⁹B) and (n+¹⁰B) have been obtained. Further these data are planned to use for extrapolation of the cross sections of astrophysical radiative neutron capture to the area of very low energies. The Work is executed within the framework of the Project STCU 3081 at financial support of the State Department of USA. (author)
