 note = {A new inter-molecular collision scheme is proposed, which conserves augular momentum in a collision cell as well as momentum and kinetic energy. The scheme is composed of two stages of calculation. In a first or conventional stage, velocities of collision molecules are calculated according to the conservation law of momentum and kinetic energy. In the second stage, positions of the molecules are adjusted in order that the angular momentum is conserved., 資料番号: NALSP0014007, レポート番号: NAL SP-14},
