| Popis: | We present a theoretical study of $K$-shell photodetachment of ${\mathrm{C}}_{2}{}^{\ensuremath{-}}$ and ${\mathrm{C}}_{3}{}^{\ensuremath{-}}$ ions. The calculations were carried out using the complex Kohn variational method. Our study addresses the recent observation that what appears as a single, narrow shape resonance close to threshold in the $K$-shell photodetachment of ${\mathrm{C}}^{\ensuremath{-}}$ splits into several peaks in the longer ${\mathrm{C}}_{n}{}^{\ensuremath{-}}$ carbon anion chains, with the number of peaks increasing with increasing $n$ values. We argue that the number of expected peaks is related to the number of symmetry-equivalent carbon atoms. |
