摘要：

We have measured the correlated center-of-mass (c.m.) motion and energy sharing of the three massive Coulamb-interacting particles H+ + H+ + H- with total energy of a few eV. We measured in time coincidence the lab frame energy and angle of all three particles produced from excited 4 keV H-3(+) formed in collisions with He. For each triple coincidence, we found the c.m. energy of each particle and the c.m. correlation angle between the two H+. The c.m. energy data, displayed on a Dalitz plot, reveals the high degree of correlated motion of the three massive charged particles.
