She sensed a flow of energy particles from various points in her body to other points.

Loosely speaking, then, we live in a world of matter particles and energy particles.

"The highest energy particles are only produced with cosmic rays," he said.

The aim of the project was to study high and ultra-high energy particles.

My area of physics is quite removed from high energy particles.

I expanded so as to avoid the gentle energy particles that fanned the area.

Very high energy particles would be generated near the black hole by the in-falling matter.

Without the deflection of the magnetic field, high energy particles coming from the sun will strike straight on the surface.

The source of such high energy particles has been a mystery for many years.

Around 1963 his interest shifted to high energy particles in the aurora.
