Learning Goals

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


Explanation and Exercise Guide


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•103 n/cm2s 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]).

Safety Aspects


Equipment

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