Closed form solution for the self-resonances in a short Josephson   junction
  We present a closed form solution for the self-resonances in a short Josephson tunnel junction. This solution is alternative to the well known textbook result \cite{Barone,Kulik} based on a series expansion. Results are derived for the up-to-date case of a $0 - \pi$ junction.
