Hello! If I have a beam of positively (single) charged molecular ions (they can be either bunched on continuous), and I want to end up with a decelerated (close to stationary) ensemble of neutral molecules (e.g. to trap them in a MOT trap), is there a way to reduce the velocity of the charged ions using simple electrodes (I know quite well the mean energy of the ions and the spread) and then somehow add one electron to these ions in the region of interest and then trap the resulting neutral molecules? Can someone point me towards some readings that did something similar? Thank you!
