  • Abstract
    An image-processing system has been used to measure tree branch lengths and fork angles in PMMA. A logarithmic distribution of branch lengths has been found, while the mean value of the forking angle is 65.7 degrees . Treeing is discussed in terms of mechanical and electronic breakdown mechanisms.
