    "abstract": "The kinetic energy distribution of D$^+$ ions resulting from the interaction\nof a femtosecond laser pulse with D$_2$ molecules is calculated based on the\nrescattering model. From analyzing the molecular dynamics, it is shown that the\nrecollision time between the ionized electron and the D$_2^+$ ion can be read\nfrom the D$^+$ kinetic energy peaks to attosecond accuracy. We further suggest\nthat more precise reading of the clock can be achieved by using shorter fs\nlaser pulses (about 15fs).",
