Stevenson, B

The method employed to curve-fit the exponential and Bessel functions as described can be adapted readily to curve-fit any function that can be expanded in a power series or is itself a polynomial of any order. The reason why these two functions were singled out is that they are the ones most frequently encountered in nuclear reactor laboratory experimentation: the exponential function with half-life and radiation beam attenuation and the Bessel function in the radial neutron flux distribution in homogeneous circular cylindrical geometry. The method has proved itself to be exceedingly useful and is remarkably easy to implement and execute.
