The photodisintegration cross section of radioactive {sup 241}Am has been obtained for the first time using monoenergetic {gamma}-ray beams from the HI{gamma}S facility. The induced activity of {sup 240}Am produced via the {sup 241}Am({gamma},n) reaction in the {gamma}-ray energy range from 9.5 to 16 MeV was measured by the activation technique utilizing high resolution HPGe detectors. The {sup 241}Am({gamma},n) cross section was determined both by measuring the absolute {gamma}-ray flux and by comparison to the {sup 197}Au({gamma},n) and {sup 58}Ni({gamma},n) cross section standards. The experimental data for the {sup 241}Am({gamma},n) reaction in the giant dipole resonance energy region is compared with statistical nuclear-model calculations.
