Abstract : The theory for the calculation of atomic transition probabilities is reviewed. Various useful formulae are given. The experimental and theoretical values by different authors are compared and listed for a number of transitions in hydrogen, lithium, nitrogen, oxygen (I and II), sodium, potassium, rubidium, and cesium. For several transitions for which previous experimental or theoretical results did not exist, values were obtained using the Coulomb approximation method of Bates and Damgaard (Phil. Trans. Roy. Soc. (London) A242, 101 (1949)). Probabilities of electric quadrupole and magnetic dipole transitions in NI, NII, OI and OII were also tabulated. (Author)
