Gold-coated zinc (Zn@Au) NP mass calculation for a cylindrical target with a 0.8-cm diameter.
| Variable | First measurement (14.15 MeV) | Second measurement (8.00 MeV) |
|---|---|---|
| Target entrance energy (MeV) | 14.15 | 8.00 |
| Target exit energy [threshold energy of 66Zn(p, n)66Ga interaction] (MeV) | 5.00 | 5.00 |
| Thick target thickness (TTT)a (g/cm2) | 0.476 86 | 0.1226 |
| Target mass (TTT × π × 0.42) (g) | 0.239 7 | 0.0616 |
a
TTT was calculated as the projected ranges of protons between the entrance and exit energies in a thick target of Zn@Au NPs.
