Abstract: 
We report the first experimental observation of magnetic field effects on dielectronic recombination (DR) via highly excited Rydberg levels. Crossed static electric and magnetic fields E-y and B-z were imposed on the collision region in high resolution DR measurements with Li-like Cl14+ ions at the heavy ion storage ring TSR in Heidelberg. Enhancement of DR rate coefficients ct for the group of high Rydberg states attached to the 2P(1/2) and 2P(3/2) series limits was observed when motional electric fields E-y up to 380 V/cm were introduced. The associated enhancement rate d alpha/dE(y) which we found to be constant at least for E-y less than or equal to 100 V/cm decreased by almost a factor of 2 when the longitudinal field B-z was increased from 20 to 69 mT.
