- Radiative Transition Probabilities and Lifetimes for the Band Systems () of the Isovalent Molecules BeF, MgF and CaF Marina Pelegrini Ciro S. Vivacqua Orlando Roberto-Neto Fernando R. Ornellas Francisco B. C. Machado Física, Astronomía y Matemáticas Accurate potential energy curves, transition moments, spectroscopic constants, radiative transition probabilities,and lifetimes for the states X2Σ+ and A2Π of BeF, MgF and CaF are reported using high level calculations.Diagonal transitions dominate for the A2Π→X2Σ+ system. Radiative lifetimes for ν = 0 are predicted to be6.81 ns, 7.16 ns and 19.48 ns, respectively for BeF, MgF and CaF. The result calculated for the CaF moleculeare in excellent agreement with the experimental result equal to 21.9±4.0 ns. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435607 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4A Vol.35
