Tracking the baryon number with nuclear collisions

Baryon quantum number is found to be conserved since baryogenesis in the early Universe. Conventionally, each fractionally charged valence quark is understood to carry one-third of a baryon number. An alternative hypothesis posits that baryon number is instead carried by a baryon...

Inscription of Quasi-Sinusoidal Surface Relief Optical Gratings in ZEONOR™ Cyclic Olefin Polymer by a 10.5 MeV N4+ Ion Microbeam at Low Implanted Fluences

Direct writing of microstructures in ZEONOR™ cyclic olefin polymer, using a high-energy medium-mass ion microbeam, was proposed and demonstrated. Microbeams of 10.5 MeV N4+ ions were used. The implanted fluences were between 2.5·1012 and 2.0·1013 ion/cm2. The microstructures were...
