Study of the charge exchange process at low energy with REXTRAP Original Research Article

The efficiency of the radioactive-ion collection Penning trap REXTRAP at REX-ISOLDE has been studied for noble-gas ions cooled by collisions in a buffer gas of Ne atoms. The number of cooled ions has been recorded as a function of the cooling time. From these measurements, information concerning the charge exchange process between ions and atoms present in the buffer gas can be deduced.
