Sub-femtosecond resolution wave packet measurements using correlated pairs

Summary form only given. Correlation offers a new route to time resolved measurements. Exploiting correlation we measure H/sub 2//sup +/ double ionization dynamics with sub-femtosecond precision and we measure vibrational wave packet dynamics in D/sub 2//sup +/ with ∼0.03- Angstrom, ∼200-Attosecond precision.
