A preparation of thin flat target for RD lifetime measurements

Abstract

An extreme flatness for a target surface is the most necessary in recoil distance method (RDM). A suitable technique was used for preparing a La target. The {sup 139} La target of thickness 0.22 mg/cm{sup 2} was evaporated onto a very flat soft Au foil of thickness 2 mg/cm{sup 2}. This target was successively used for lifetime measurements of the excited nuclear states in {sup 145} Sm nucleus through the nuclear reaction {sup 139} La ({sup 10} B, 4 n) {sup 145} Sm. Background {gamma} rays produced by the {sup 10} B irradiation for the Au backing and the Pb stopper without the La target were measured. Besides that, the {gamma} rays from residual activities were also measured. 3 figs.
