Triply differential cross section for the ionization of inner orbitals of thymine by electron impact is investigated at low impact energy. Results of first and second Born calculations performed at 250 eV incident energy with coplanar asymmetric geometry are compared with recent experiments. The initial state of the target is described by one single center wavefunction. It is observed that second Born calculations improve substantially the agreement with experiments.
