Two-body Coulomb explosion processes of ethane (CH3CH3) and its isotopomers (CD3CD3 and CH3CD3) induced by an intense laser field are investigated by a coincidence momentum imaging method. From the yield ratios of H3+, H2D+, HD2+, and D3+ ejected from CH3CD3+ induced by an ultrashort-pulsed intense laser field, nearly statistical randomization of H and D atoms called hydrogen atom scrambling was identified.
