摘要：

Delayed gamma spectrum is the fingerprint of uranium materials in the arms control verification technology. The decay chain was simplified into basic state linear chain and excitation state linear chain to calculate and analyze the delayed gamma spectra of fission products. Formulas of the changing rule for nuclide number before and after zero-time were deduced. The C program for calculating the delayed gamma spectrum data was constructed, and related experiments were conducted to verify these formulas. Through analysis of the delayed gamma counts of several nuclides, the calculated results are found to be consistent with experimental values. © 2019, Editorial Board of Atomic Energy Science and Technology.
