Abstract It is shown that in a plasma produced on the surface of a sample consisting of a natural mixture of mercury isotopes, ∼104−105 201Hg nuclei can be excited into the low-lying isomeric level 1/2− (1.561 keV) by an ultrashort laser pulse with energy ≈1 J, duration ≈200 fs, and intensity ≈1016 W/cm2 and the lifetime of the level can be determined. Possible mechanisms leading to the excitation of 201Hg nuclei by photons and electrons in a dense, hot plasma are examined and the cross sections of the processes are estimated. Schemes for detecting the effect are proposed.
