Cannon for neutral particles

The manipulation of neutral particles*

The written version of my lecture is a personal account of the development of laser cooling and trapping. Rather than give a balanced history of the field, I chose to present a personal glimpse of how my colleagues and I created our path of research. I joined Bell Laboratories in the fall of 1978 after working with Eugene Commins as a graduate student and post-doc at Berkeley on a parity noncon...

Dynamics of spin–polarized neutral particles, such as neutrons or neutral atoms and molecules, in magnetic fields is studied. A new regime of motion is found where particles move mainly in one direction forming a well–collimated beam. This regime suggests a mechanism for creating devices emitting directed beams of neutral particles.

Behavior of Neutral Particles under Charge Conjugation

Some properties are discussed of the 8', a heavy boson that is known to decay by the process 0'~m.++21. . According to certain schemes proposed for the interpretation of hyperons and E particles, the 8' possesses an antiparticle 8 distinct from itself. Some theoretical implications of this situation are discussed with special reference to charge conjugation invariance. The application of such i...

Nonlinear dynamics in an alternating gradient guide for neutral particles

Neutral particles can be guided and focussed using electric field gradients that focus in one transverse direction and defocus in the other, alternating between the two directions. Such a guide is suitable for transporting particles that are attracted to strong electric fields, which cannot be guided using static fields. Particles are only transmitted if their initial positions and transverse s...
