Peak position consistency energy spectrum searching method for neutron activation element analysis

The invention discloses a peak position consistency energy spectrum searching method for neutron activation element analysis. According to the peak position consistency energy spectrum searching method, files in a spectral form knowledge base are numbered, and index files are established according to peak position information, wherein each index file is a binary number with the number of digits equal to the number of spectral forms; according to the peak position information of an actually measured spectral form, corresponding Boolean operation is conducted on the index files, and a spectral form meeting a searching requirement is obtained from the spectral form knowledge base. By the adoption of the peak position consistency energy spectrum searching method, the spectral form with the peak position identical with that of the actually measured spectral form can be rapidly and accurately found from the spectral form knowledge base, and especially when the number of the spectral form files in the spectral form knowledge base is large enough and far larger than the total number of channels of the spectral form files, the peak position consistency energy spectrum searching method has remarkable advantages.
