We use the generator coordinate method to study the {sup 12}C( n,{gamma}){sup 13}C and {sup 12}C( p,{gamma}){sup 13}N reactions, as well as the {sup 13}C and {sup 13}N spectroscopy. The {sup 12}C wave functions are defined by three {alpha} particles in a regular triangle of size R{sub C}. Different configurations are considered, in order to analyze clustering effects. It is shown that spectroscopic properties of {sup 13}C and {sup 13}N are sensitive to the {sup 12}C wave function; reasonable agreement with experiment is found with R{sub C} values minimizing the {sup 12}C binding energy. The present study supports the suggestion of a halo structure for the 1/2{sup +} excited state in {sup 13}C. The neutron and proton capture cross sections are in good agreement with experiment. Finally, we analyze distortion effects in the {sup 12}C+n wave functions. {copyright} {ital 1997} {ital The American Physical Society}
