摘要: Abstract Accurate values of electric dipole (E1) amplitudes along with their uncertainties for a number transitions among low-lying states Mg + , Ca Sr and Ba are listed by carrying out calculations using relativistic all-order many-body method. By combining experimental wavelengths these amplitudes, we quote transition probabilities, oscillator strengths lifetimes many short-lived excited the above ions. The in radiative properties also quoted. We give quadrupole (E2) magnetic (M1) metastable ions performing similar calculations. Using calculated E1, E2 M1 matrix elements, have estimated allowed states. These quantities further compared available from other theoretical studies data literature. present will be useful astrophysical observations, laboratory analysis simulations spectral considered alkaline-earth metal
