Description
- The 208Pb target, manufactured by Oak Ridge National Laboratory, is a 1 in. diameter circular foil of 99.09% enriched 208Pb, with an approximate thickness of 12 mils.
- A description of the target can be found in P. Martel et al., "Nuclear Targets for a Precision Measurement of the Neutral Pion Radiative Width," NIMA 612 (2009) 46-49.
