Cyclic C $_{4}^{+}$ as the carrier of the diffuse interstellar band at 503.9 nm?

Serge. A. Krasnokutski, Lisa Ganner, Milan OnÄÃ¡k +5

The diffuse interstellar bands (DIBs) have remained a mystery in astronomy since their discovery over a century ago. The only currently known carrier is C $_{60}^{+}$ responsible for…

Autodetachment of diatomic carbon anions from long-lived high-rotation quartet states

Viviane C. Schmidt, Roman ÄurÃk, Milan OnÄÃ¡k +11

Highly excited C $_{2}^{-}$ ions prominently feature electron detachment at a mean decay time near 3 milliseconds with hitherto unexplained origin. Considering various sources of un…

Unimolecular processes in diatomic carbon anions at high rotational excitation

Viviane C. Schmidt, Roman ÄurÃk, Milan OnÄÃ¡k +11

On the millisecond to second time scale, stored beams of diatomic carbon anions C $_{2}^{-}$ from a sputter ion source feature unimolecular decay of yet unexplained origin by electron…
