Range of 1-3 MeVNe22Ions in Al and the Analysis of SomeNa24Recoil Data

Abstract

Beams of ${\mathrm{Ne}}^{22}$ ions from a Van de Graaff accelerator were stopped in stacks of aluminum leaf which were then analyzed for Ne content with a high-sensitivity mass spectrometer. The mean ranges projected along the beam direction for 1.0-, 2.0-, and 2.8-MeV ${\mathrm{Ne}}^{22}$ ions were found to be (0.35, 0.54, and 0.67) ±0.02 mg/${\mathrm{cm}}^2$ of Al, respectively. The half-widths of the range curves were 0.20±0.05 mg/${\mathrm{cm}}^2$.
