Rotational state-changing collisions of C${}_2$H${}^{-}$ and C${}_2$N${}^{-}$ anions with He under interstellar and cold ion trap conditions: a computational comparison

Jan Franz, Barry Mant, Lola González-Sánchez +2

We present an extensive range of quantum calculations for the state-changing rotational dynamics involving two simple molecular anions which are expected to play some role in evolu…
