The electron-impact ionization cross sections are reported for neutral beryllium (Be) and its ions (Be⁺, Be2⁺, and Be3⁺) within the frameworks of the Binary Encounter Dipole (BED), Coulomb-Born Exchange (CBE), and Distorted Wave (DW) methods. The ionization cross sections have been calculated for energies ranging from the ionization threshold up to 100 eV, considering both the ground state and the first excited state of beryllium. The BED method exhibited excellent agreement with the experimental data for Be⁺ within the energy range of 52–116 eV. Furthermore, a detailed comparison has been performed between the calculated cross sections and existing theoretical and experimental data. We have additionally calculated the Maxwell rate coefficients for direct ionization in the ground state of neutral beryllium (Be) and its ions over an electron energy range extending up to 10 keV. These results provide valuable insights for plasma modeling by offering critical data for understanding the interaction dynamics of beryllium in plasma environments.
