【 摘 要 】

We report experimental observation of the long predicted but experimentally elusive Efimov state of4He trimer by means of Coulomb explosion imaging. We show spatial images of an Efimov state, confirming the predicted size and a typical structure where two atoms are close to each other while the third is far away.
