Abstract

Fe-Se binary cluster ions produced by direct laser ablation,were studied with a tandem time-of-flight masss pectrometer.It was found that FenSen+,FenSen-1+ in cluster cations,FenSen-FenSen+1-in cluster anions were main compositions of binary cluster ions.The photodissociation of cations FenSen+showed that FenSen+,FenSen-1+ were main photofragments,confirming their special stablity.The possible structures of Fe2Se2+ were calculated by Density Function Theory(B3LYP/LANL2DZ).
