Knock-on (rugby League)
This list of rugby league terms is a general glossary of the terminology used in the sport of rugby league football. The sport has accrued a considerable amount of jargon to describe aspects of the game. Many terms originate from the Laws of the Game. A number of aspects of the game have more than one term that refers to them. Different terms have become popularly used to describe an aspect of the game in different places with notable differences between the northern and southern hemispheres. Where words in a sentence are also defined elsewhere in this article, they appear in italics. 0–9 : Every time a player is tackled, all defenders, apart from a maximum of two markers, have to retreat 10 metres from the play-the-ball area. : A player selected as a back-up to the official 17 man squad for a game. The 18th man usually warms up with the team prior to a match and may be called into the team if one of the 17 players is injured or ill prior to the start of the match. The term ...

The tour was marred by on-pitch violence, which the match officials did not adequately control and the relative absence of cameras compared to the modern game made citing and punishment after the fact unlikely.

Knock-on Electron
A delta ray is a secondary electron with enough energy to escape a significant distance away from the primary radiation beam and produce further ionization, and is sometimes used to describe any recoil particle caused by secondary ionization. The term was coined by J. J. Thomson. Characteristics A delta ray is characterized by very fast electrons produced in quantity by alpha particles or other fast energetic charged particles knocking orbiting electrons out of atoms. Collectively, these electrons are defined as delta radiation when they have sufficient energy to ionize further atoms through subsequent interactions on their own. Delta rays appear as branches in the main track of a cloud chamber (See Figs. 1,2). These branches will appear nearer the start of the track of a heavy charged particle, where more energy is imparted to the ionized electrons. Delta rays in particle accelerators Otherwise called a knock-on electron, the term "delta ray" is also used in high energy physic ...
