Molecular alignment in degenerated dissociation channels in strong laser fields

Abstract In this work, we study strong-field molecular alignment in, for the first time, degenerated channels following the same charged states of molecules. By measuring the angular distribution of dissociation fragments from two degenerated N+ + N+ channels of N2, we observe an opposite angular di...
