Abstract In this paper, we propose a new collision cross section set for mercury which revises the original set summarized by Hayashi in 1989. Hanne reported three excitation collision cross sections (63P0, 63P1, 63P2) determined from an electron beam experiment in 1988. As a matter for regret, no attentive consideration was given to combining these three excitation cross sections with the cross section set of Hayashi. Therefore we propose a new set where these three excitation cross sections are included. In this study, other two excitation cross sections (61P1, 63D3) except for the three excitation collision cross sections (63P0, 63P1, 63P2) are taken from the original set of Hayashi. The momentum transfer cross section and the ionization collision cross section are also taken from Hayashi. A Monte Carlo Simulation (MCS) technique is applied for evaluating our new cross section set. The present results of the electron drift velocity and the ionization coefficient are compared to experimental values. Agreement is secured in relation to the electron drift velocity for 1.5 Td < E/N < 7 Td and to the ionization coefficient for 400 Td < E/N < 3000 Td, where E/N (V · cm2) is the reduced electric field, E (V/cm) is the electric field, N (1/cm3) is the number density of mercury atoms at 0?, 1 Torr, E/N is also equal to 2.828 × 10−17 E/p0 from the relation of the ideal gas equation, p0 (Torr) is gas pressure at 0?, 1 Torr = 1.33322 × 10−2 N/cm2 and 10−17 V/cm2 is called 1 Td. Thus it is ensured that our new cross section set is reasonable enough to be used up to 100 eV when considering with the electron drift velocity and the ionization coefficient.
