%X The exact mass of kidney bean slices and Mylar film was measured before and after the irradiation of 50 keV N+, with doses ranging from 1×1015 ions/cm2 to 1×1017 ions/cm2. The result shows that the mass of kidney bean slices decreased 151 μg/cm2 with the dose of 3×1016 ions/cm2, while the Mylar films did not show visible mass loss up to the dose of 7×1016 ions/cm2. The obtained sputtering yield is about 560 atoms/ion, which is much larger than the simulated result using TRIM96 Code. This high-yield sputtering phenomenon was explained according to the intrinsic structure and composition of botanic samples.
