We have used a high collimated neutral chromium atomic beam to write periodic nanometer-scale structures by depositing an atomic beam of 52 Cr through an off-resonant laser standing wave with the wavelength of 425.55 nm onto a silicon substrate. The resulting nanolines exhibit a period of 215 ยฑ 3 nm
