Abstract
Energy levels, line strengths, weighted oscillator strengths, radiative decay rates and electron-impact collision strengths are presented for neon-like Si V which is important for astrophysical and laboratory plasmas.Atomic data are calculated with the SUPERSTRUCTURE package using scaled Thomas-Fermi-Dirac-Amaldi potentials. Relativistic corrections are introduced according to the Breit-Pauli approach. The 1s22s22p6, 1s22s22p53l, 1s22s2p63l and 1s22s22p54l (l ≤ n - 1) configurations are included to obtain the corresponding 75 energy levels of Si V. Non-relativistic collisional data are calculated using the UCL-Distorted Wave code which are transformed to fine-structure data by UCL-JAJOM code. The collision strengths are obtained for seven incident impact electron energies: 15, 30, 45, 60, 75, 90 and 105 Ry. Some of these data are compared with available experimental andtheoretical data.
