Abstract
The form of the spacial distribution function of ions and electrons in an irradiated liquid is not accurately known and several types of function have been assumed by different workers. The various forms are compared and used in the calculation of electron–solute reaction yields in liquid cyclohexane. Our previously used semi-empirical distribution function (YSE) and a power function (YP) give satisfactory I results, but a three dimensional, single parameter Gaussian (YG1) and a delta function (YD) do not. The prescribed diffusion approximation has also been inserted into the model for comparison with earlier work. No improvement was obtained. Whereas our previous approximations may lead to an underestimate of the geminate neutralization times, the prescribed diffusion approximation may lead to an overestimate of them.
