Popis: The possibility of observing the stimulated de-excitation of nuclear isomers (SDENI) in plasma (plasma lifetime ∼1.5 ps, temperature of electrons ∼ 10 keV) formed by the impact of a high-power laser pulse (∼1018 W cm−2) on a target is studied experimentally. Preliminary experiments are carried out with the 110mAg (T1/2 = 250 days) and 186mRe (T1/2 = 2 × 105 years) isomers. A weak SDENI effect is observed only for the 110mAg isomer on a platinum backing.
