Physics 17 Spring 1997 Lab 6 - Neutron Activation of Silver
Ment is called neutron activation. In this experiment, we will activate two isotopes of silver, Ag 107 and Ag 109, by neutron bombardment and measure their half lives. The apparatus you will use consists of a General Radio counter, a high voltage power supply, a large block of paraffin, a Geiger tube, a silver foil and a neutron source. A ... Retrieve Document
