text_A: The Fate of the Furious was the highest grossing film in 2017.
text_B: The helium trimer is a weakly bound molecule consisting of three helium atoms .. Van der Waals forces link the atoms together .. The combination of three atoms is much more stable than the two atom helium dimer .. helium dimer. helium dimer. The three atom combination of helium-4 atoms is an Efimov state .. Efimov state. Efimov state. Helium-3 is predicted to form a trimer , although ground state dimers containing helium-3 are completely unstable .. Helium-3. Helium-3. Helium trimer molecules have been produced by expanding cold helium gas from a nozzle into a vacuum chamber .. Such a set up also produces the helium dimer and other helium atom clusters .. helium dimer. helium dimer. The existence of the molecule was proven by matter wave diffraction on a diffraction grating .. matter wave. matter wave. diffraction grating. diffraction grating. The kind of grating used needs to have empty space between the bars , so that molecules can pass through , glass would stop helium .. Properties of the molecules can be discovered by Coulomb explosion imaging in which a laser ionizes all three atoms simultaneously , and then three ions fly apart and are then detected .. Coulomb explosion imaging. Coulomb explosion imaging. The helium trimer is large , being more than 100 A , which is even larger than the helium dimer .. helium dimer. helium dimer. The atoms are not arranged in a equilateral triangle as might be expected , but form random shaped triangles .. Interatomic Coulombic decay can occur when one atom is ionised and excited .. It can transfer energy to another atom in the trimer , even though they are separated .. However this is much more likely to occur when the atoms are close together , and so the interatomic distances measured by this vary with half full height from 3.3 to 12 A .. The predicted mean distance for Interatomic Coulombic decay in 4He3 is 10.4 A .. For 3He4He2 this distance is even larger at 20.5 A .
