Knock-on (rugby League)
Rugby league football has accrued considerable jargon to describe aspects of the game. Many terms originate in the Laws of the Game. Some aspects of the game have more than one term referring 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. Words in a sentence which are also defined elsewhere in this glossary appear in italics. 0–9 A B C D E F G H I K L M O P R S {{defn, 1=The six-tackle rule was introduced in 1972, modifying the ...

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. The term 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 energ ...

Knock-on Effect
In the social sciences, unintended consequences (sometimes unanticipated consequences or unforeseen consequences, more colloquially called knock-on effects) are outcomes of a purposeful action that are not intended or foreseen.
