description of experimental irradiations C215400100013
FACILITY (LINAC,1USALAS) Irradiations were performed at the C215400100014
Los Alamos National Laboratory's Neutron Science C215400100015
Center (LANSCE), proton beams of approximately 90-120 C215400100016
nA intensities with incident energies of 100 and C215400100017
200MeV. C215400100018
SAMPLE Thorium foil stacks were used as a sample. Each stack C215400100019
contained two sets of six thin thorium foils C215400100020
separated by aluminum energy degraders. C215400100021

METHOD Amount of reduced 227Ac was determined from its decay C215400200014
product 215Po. To reach equilibrium with 215Po parents C215400200015
to facilitate spectroscopic measurement required C215400200016
approximately 100-day waiting period following C215400200017
