“…From the results of fitting, the following values were obtained: α = 1.37, β = 0.52 and γ = 1.44. Previously, a technical team from IAEA [23], Biancheria [24] and Schultz [22] recommended α = 2.5 ± 1.5 for the Loeb equation, β = 0.5 for the Maxwell-Eucken equation, and γ = 1.5 for the Schultz equation. In the present study, β = 0.5 recommended by Biancheria agreed well with β = 0.52 which was determined from the experimental value.…”
