Asymmetric Images with X-Radiation

Article metrics


CONFIRMING our letter of July 16 on asymmetric haloes, we have found that the bands can be produced on one, two adjacent, three, or all sides of a square (lead), and when an obstacle is placed at or over one side the corresponding band only vanishes. These effects are independent of the incidence of the radiation. With V-shaped aperture, the apex resting on the plate, the bands on one side are sharply defined, and twice bent; on the other there are several, and they are diffuse and fainter.
