Recollision physics and attosecond pulse generation meld the precision of optics with collision physics. As a follow-up to our previous work

we reveal a new direction for the study of electronic structure and multielectron dynamics by exploiting the collision-physics nature of recollision. We show experimentally that

by perturbing recollision trajectories with an infrared field

photorecombination time delays can be measured entirely optically using the Cooper minimum in argon as an example. In doing so

we demonstrate the relationship between recollision trajectories and the transition moment coupling the ground and continuum states. In particular

we show that recollision trajectories are influenced by their parent ion

while it is commonly assumed they are not. Our work paves the way for the entirely optical measurement of ultrafast electron dynamics and photorecombination delays due to electronic structure

multielectron interaction

and strong-field-driven dynamics in complex molecular systems and correlated solid-state systems.
