WebMay 3, 2004 · The theory is based on the Wesslau molecular‐weight distribution function and the results are in much better agreement in the case of many polymers than are the theoretical calculations of Inokuti based on a normalized Poisson distribution equation or the theory of Charlesby—Pinner based on a random molecular‐weight distribution. WebOct 22, 2004 · The apparent G values of crosslinking (crosslinks per 100 eV absorbed dose) are calculated using the Charlesby-Pinner relationship, and shown to be dramatically lower than for the corresponding MeV ion beams. This decrease is attributed due to the reduced ion track radius and an increase in the density of crosslinking points.
