Abstract： We present experimental evidence to reveal the mechanism of long-range penetration of low-energy ions in botanic samples. In the 100 keV Ar+ ion transmission measurement, the result confirmed that low-energy ions could penetrate at least 60μm thick kidney bean slices with the probability about 1.0 x 10-5. The energy spectrum of 1 MeV He+ ions penetrating botanic samples showed that there existed peak of count of ions with little energy loss. The probability of the low-energy ions penetrating the botanic sample is almost the same as that of the high-energy ions penetrating the same samples with little energy loss. The results indicate that there are some micro-regions with the mass thickness less than the projectile range of low-energy ions in the botanic samples and they result in the long-range penetration of low-energy ions in botanic samples.
