Abstract

A chemically selective laser ion source based on resonance ionization of atoms in a hot cavity was applied for study of short‐lived tin isotopes at the heavy ion accelerator UNILAC/GSI. Tin atoms were ionized by a three‐step resonance laser excitation of an autoionizing state. Yields of fusion‐produced 108Sn and 108In isotopes were compared with the plasma ion source FEBIAD‐B3. The total efficiency of tin ionization was determined to be 8.5%, whilst the indium isobar ionization was suppressed by a factor of 12. An experimental run on study of decay properties of extremely neutron deficient isotopes 101–103Sn has been carried out.
