Direct capture in the ${}^{130}$Sn(n,$\gamma$)${}^{131}$Sn and ${}^{132}$Sn(n,$\gamma$)${}^{133}$Sn reactions under $r$-process conditions

The cross sections of the ${}^{130}$Sn(n,$\gamma$)${}^{131}$Sn and ${}^{132}$Sn(n,$\gamma$)${}^{133}$Sn reactions are calculated in the direct capture model at low energies below 1.5,MeV. Using recent data from (d,p) transfer experiments on ${}^{130}$Sn and ${}^{132}$Sn, it is possible to avoid global input parameters with their inherent uncertainties and to determine all input to the direct capture model by local adjustments. The calculated direct capture cross sections of ${}^{130}$Sn and ${}^{132}$Sn are almost identical and have uncertainties of less than a factor of two. The stellar reaction rates $N_A < \sigma v >$ show a slight increase with temperature. Finally an estimate for the influence of low-lying resonances to the stellar reaction rates is given.
