EXPERIMENTS WITH TRAPPED HYDROGEN-ATOMS AND NEUTRONS

The earliest trapped atom coherent resonance experiments were with mat erial traps or bottles. In the atomic hydrogen maser the atoms are tra pped inside a teflon-coated quartz bulb for about a second. Neutrons h ave been trapped for hundreds of seconds in suitably coated bottles or in superconducting magnetic traps. Results from experiments with trap ped atoms and neutrons are given.
