Abstract. Impact of powerful nanosecond electromagnetic impulses (NEMI) on fusions containing lead and bismuth is considered. The main controlled property is chemical composition. Special pulse generators are used for influence. They produce pulses of the positive polarity with duration of 1 nanosecond on a half-height, with amplitude of 6-10 kV and repetition frequency of 1 kHz. Processing of NEMI is carried out directly in a crucible into which the copper tube or a core is inserted. Outputs of the generator connect with a crucible and a tube. Time of processing is tens of minutes. The level of α-radiation and β-radiation of solid metal is measured before and after processing. There are given the results of 4 experiences in which the reduction of amount of bismuth by 8-10% and the same in size increase of amount of lead is noted. For one of experiences the analysis of the chemical composition is carried out on three devices, various on type. The theory of electronic capture under the influence of NEMI and change of isotope structure without change of mass of a kernel are offered as theoretical base. Results which describe transformation of tens of grams of bismuth into the same amount of lead are absent in available literature.
