Abstract
Theoretical results have been computed to complement recent measuremen ts by Scheer et al. [Bull. Am. Phys. Sec. 42, 1026 (1997)], which yiel ded electron affinities (EA) of excited states of the ground configura tion of Sn-. Our relativistic configuration-interaction values for the position of the excited Sn-with respect to the negative ion ground st ate are EA(D-2(3/2)) = 5903 cm(-1) (0.732 eV), and EA(D-2(5/2)) = 6493 cm(-1) (0.805 eV). Triple excitations make a significant contribution . Magnetic dipole hyperfine-structure constants (A) and M1 transition probabilities are also reported.
