Developed By
Section of Radiochemistry Institute of Chemistry Faculty of Mathematics and Natural sciences University of Oslo

Learning Goals
Understand the principle of neutron activation Deconvolution of a decay curve with two components

Theory
Neutron Activation of Ag with a Pu\Be n-source How to Calculate End-of-Irradiation Yields of Ag-isotopes

Experimental Procedure
Neutron Activation of Ag How to Measure the Decay of n-activated Silver Analyzing a Two-component Decay Curve Analyzing the Production Curve of n-activated Ag

Questions for the Students
Use the cross-sections from the nuclear chart, the half life and a thermal neutron-flux of 2•10 3 n/cm 2 s to estimate the relative amount you will produce for a 144 s irradiation. Which nuclei will be dominant?

Determine what kind of gamma radiation to expect from the silver isotopes produced in the irradiation and their associated relative intensity (e.g. from [[|Berkeley/Lund database]]).

Equipment
Need silver disk and a neutron source, or if using RoboLab an internet connection.
