Abstract
A new method to select the initial guess spectrum is presented. Neutron spectra unfolded from Bonner sphere data are dependent on the initial guess spectrum used in the unfolding code. The method is based on a catalogue of detector count rates calculated from a set of reported neutron spectra. The spectra of three isotopic neutron sources 252Cf, 239PuBe and 252Cf/D2O, were measured to test the method. The unfolding was carried out using the three initial guess options included in the BUNKIUT code. Neutron spectra were also calculated using MCNP code. Unfolded spectra were compared with those calculated; in all the cases our method gives the best results.
