Abstract
In this paper, attention is drawn to a deficiency in the conventional method used to extrapolate the pulse-height distributions recorded using pulse ionization fission chambers to zero amplitude. A simple expression for an appropriate correction factor is derived. It is shown that for a representative case, the conventional method involving horizontal extrapolation, underestimates the number of missed fission fragments by as much as 30%. A systematic error of this magnitude in a correction even as small as 1%, is highly significant when compared with the accuracy to which the 235U fission cross-section is currently estimated to be known.
