Description

The absolute electrofission cross sections of Au and Ta were measured in the range 25--180 MeV. The deduced photofission cross section shows, for both Au and Ta, a pronounced dip around the photopion threshold (∼140 MeV). This (γ,f) dip is interpreted as a consequence of a probable photopion absorption in a ''stopped pion regime.''
