Abstract
We have studied three pairs of prominences, two of them clearly showing the effect of interaction by a dynamical plasma bridge. The other one was a superimposed optical pair which also showed, after being spectroscopically studied, the possible effect of interaction. We have calculated the atom density in the prominence and bridges, and applied the Goldberg-Unno method for the determination of Doppler-widths of the calcium H and K lines.
