• A method of determining the material buckling of a cylindrical subcritical assembly is described. The new technique is an improved "flux shape" method that is based upon the complete orthogonal-ity of the Bessel function. To obtain sufficient accuracy, a scintillation detector with a very thin scintillator has been used. The result indicates that the present method yields a value of buckling free from higher harmonics and end effects, with a standard deviation of 3.0 % under centric point source condition. The buckling obtained is -(7.08±0.23)×10<SUP>-4</SUP> cm<SUP>-2</SUP>. This lies between the values measured by conventional "flux shape" and "variable loading" methods, which are amenable to un-wanted effects.
