During the last decades, the study of phenomena occurring in collisions between charged particles and target atoms has grown to a field of increasing interest in both its theoretical and experimental aspects. This growing interest is due to the wide applicability of Particle Induced X-Ray Emission (PDCE) in many fields. When performing sample analysis by PIXE, one of the essential factors is the production cross section or the ionization cross section on which relics to a great extent the quantitative PIXE analysis. In this paper, we report a new empirical formula to calculate K X-ray production cross sections by alpha-particles impact for elements with atomic numbers 25 <= Z <= 30. In this formula. we introduced two parameters dependence, the atomic number Z and the projectile energy E (MeV). Our results for empirical K X-ray production cross sections are presented for selected elements and compared with other experimental as well as theoretical results; theoretical production cross sections calculated by using a personal computer program based on the ECPSSR model; and semi-empirical "reference" values. Generally, the obtained results are in agreement with theoretical prediction, reference values and with the experimental results.
