摘要：

Experimental data from transmission studies of low-energy electron scattering from caesium atoms are compared with recent theoretical data from a Breit-Pauli R-matrix (close-coupling) calculation. There is strong evidence for the observation of the (6p2)P-3(2)e resonance below the threshold for the first excited state, (6p)P-2(1/2)o, of the target atom. In a purely non-relativistic framework, this resonance corresponds to a stable bound state of the negative caesium ion in the ionization continuum. Consequently, its decay is direct evidence for relativistic effects on the autoionization process.
