Preparation of actinide targets by molecular plating for Coulomb excitation studies at ATLAS.

PDF Version Also Available for Download.

Description

Molecular plating is now routinely used to prepare sources and targets of actinide elements. Although the technique is simple and fairly reproducible, because of the radioactive nature of the target it is very useful to record various parameters in the preparation of such targets. At Argonne, {approximately}200 {micro}g/cm{sup 2} thick targets of Pu and Cm were required for Coulomb Excitation (COULEX) Studies with the Argonne-Notre Dame BGO gamma ray facility and later with the GAMMASPHERE. These targets were plated on 50 mg/cm{sup 2} Au backing and were covered with 150 {micro}g/cm{sup 2} Au foil. Targets of {sup 239}Pu, {sup 240}Pu, ... continued below

Targets of {sup 239}Pu, {sup 240}Pu, {sup 242}Pu, {sup 244}Pu and {sup 248}Cm were prepared by dissolving the material in isopropyl alcohol and electroplating the actinide ions by applying 600 volts. The amount of these materials on the target was determined by alpha particle counting and gamma ray counting. Details of the molecular plating and counting will be discussed.
