Kaneko, T. Sekine, K. Yoshihara] Appearance energy is originally the threshold energy at which récoil products begin to be observed. This was determined by /γ, γ'/ reactions. Afterwards, an alternative technique has been developed to determine it by summing up recoil energy spectrum. The latter technique assumed a step function rising at energy EO in the yield-energy relation. EO should be defined as ‘normalized appearance energy' /NAE/, because it is not threshold energy in its original sense. The NAE for isomerization from Δ to Λ /or reverse/ in Ru/acac/3 was estimated to be 29 eV, and that for free atom /or ion/ formation was calculated to be 34 eV. The 5 eV difference seems to indicate an energy interval in which isomerization effectively occurs in the recoil reaction. Akadémiai Kiadó, 1990 Kaneko I.
