Abstract: | The scintillation effects which are produced when radiation is incident on a medium containing phase changing irregularities which have power law spectra are discussed. The results are then applied to the interplanetary medium and it is concluded that the small scale sizes (≈100 km) for irregularities measured by interplanetary scintillation represent a genuine ‘outer scale’ distinct from the 106 km scales detected by space probes. It is also shown that the small scale irregularities contain discontinuities which are finite or almost finite, with a sharpness as yet undetermined. |
