Electron-capture in collisions of singly charged protonated water clusterH+(H2O)3, ions with Ar atoms is studied at the impact energy of8 keV in the frame of the COrrelated Ion and Neutral fragments Time-Of-Flight, COINTOF,technique. In contrast to methods based only on the detection of the charged fragments,dissociation induced by collisional-excitation and electron-capture induced dissociationcan be simultaneously recorded in the present set-up. The time of flight measurements ofboth the neutral and the corresponding charged species resulting from the charge-exchangeprocess provide a direct observation of the dissociation of the neutralized protonatedwater cluster. Thus, the present COINTOF method provides new valuable insights into thecollision process through the detection of produced neutral fragments. Moreover, it opensnew possibilities to measure kinetic energy release also in the dissociation of theproduced neutrals, which is our future endeavour in the development of the presentedCOINTOF set up.
