Abstract

A molecular synchrotron offers unique possibilities to study molecular collisions at low energies. For such a study, it is imperative that the velocity of the stored molecules can be tuned over a wide range. Bunching elements, used to provide the necessary longitudinal focusing forces in a synchrotron, introduce instabilities for certain velocities of the stored molecules. Here we present an experimental study of these motional resonances and show how they can be avoided. A packet of ND3 molecules is stably confined in the synchrotron as its injection velocity is continuously scanned from 60ms (Ekin=3.0cm1)to87.5ms (Ekin=6.4cm1).
