  We have studied the neutron-capture reactions 10,11B(n, g) and the role of
the 11B(n, g) reaction in seeding r-process nucleosynthesis. The possibility of
the description of the available experimental data for cross sections of the
neutron capture reaction on 10B at thermal and astrophysical energies, taking
into account the resonance at 475 keV, was considered within the framework of
the modified potential cluster model (MPCM) with forbidden states and
accounting for the resonance behavior of the scattering phase shifts. In the
framework of the same model the possibility of describing the available
experimental data for the total cross sections of the neutron radiative capture
on 11B at thermal and astrophysical energies were considered with taking into
account the 21 and 430 keV resonances. Description of the available
experimental data on the total cross sections and astrophysical S-factor of the
radiative proton capture on 11B to the ground state of 12C was treated at
astrophysical energies. The possibility of description of the experimental data
for the astrophysical S-factor of the radiative proton capture on 14C to the
ground state of 15N at astrophysical energies, and the radiative proton capture
on 15N at the energies from 50 to 1500 keV was considered in the framework of
the MPCM with the classification of the orbital states according to Young
tableaux. It was shown that, on the basis of the M1 and the E1 transitions from
different states of the p15N scattering to the ground state of 16O in the p15N
channel, it is quite succeed to explain general behavior of the S-factor in the
considered energy range in the presence of two resonances.
