2 Particle Annihilation and Creation
... 1) To compare two methods of particle creation: Stationary target versus Colliding beams. In a collision between a moving particle and one that is stationary, most of the energy is ‘wasted’ in conserving momentum and cannot go into creating mass. However, if the particles collide head-on all the ene ...

During this time window and at polarized excitation, which creates spin polarized carriers, the electron can polarize the QD nucle ...
