fusion can be used in several ways:

  1. external electronic neutron sources, uses a miniaturized particle accelerator with tritium gas to produce a burst of neutrons to initiate fission at the best time for desired yield
  2. boosting, injects a controlled amount of deuterium and/or tritium gas into a hollow core, when the device is detonated this undergoes fusion producing a large burst of neutrons increasing the fission efficiency; this permits either a reduction in amount of fissile material required or an increase in yield or both; this also permits dial-a-yield bombs having selectable variable yield
  3. staged fusion, a bomb permitting unlimited theoretical yield; also commonly called the hydrogen bomb

What kind of nuclear reaction does an atomic bomb use?

Fission bombs use fission. Fusion bombs use fusion. Although atomic bomb is usually used for fission bombs, it technically applies equally to either.


Are the a bomb and h bomb the same?

Yes and no.A-bomb or Atomic Bomb is a generic term simply meaning a bomb getting its energy from the atom. This name has become commonly used to mean Fission bomb.Nuclear Bomb is a generic term simply meaning a bomb getting its energy from the nucleus of the atom, can be used interchangeably with Atomic bomb as a generic term.Fission Bomb is a term for a specific type of Atomic/Nuclear bomb getting its energy from the fission (breaking up) of large atomic nuclei (e.g., Uranium or Plutonium).Fusion Bomb, H-bomb, or Hydrogen Bomb is a term for a specific type of Atomic/Nuclear bomb getting its energy from the fusion (combining) of small atomic nuclei (e.g., Deuterium or Tritium).Most modern Nuclear Weapons use combinations of Fission and Fusion to get desired results. This makes it hard to put them in fixed categories.Hope this helps some to clarify things.


What is the principle used in the hydrogen bomb?

Nuclear fusion.


What is the difference between an atomic bomb and a thermonuclear bomb?

They are both general terms. The term "atomic bomb" can mean any nuclear weapon, either a fission weapon or a fusion weapon (the so-called hydrogen bomb). The term thermonuclear bomb is also used in general, but it usually excludes the fusion bombs. It should be noted, however, that it takes a fission bomb to generate the heat necessary to "set off" a fusion reaction and make a fusion bomb work.


Why is an atomic bomb sometimes called a fisson bomb?

The term atomic bomb is a general one. It refers to any kind of nuclear weapon. But there are basically a couple of different types of nuclear weapon: the fission weapon, and the fusion weapon. (We can split hairs and add some, but let's not.) In a "regular" atomic or nuclear weapon, a fission weapon, subcritical masses of fissile material, usually plutonium, are driven together by conventional explosives and the thing goes off. Boom! There is fission, but no fusion. That differentiates this type of weapon from a fusion device. The term fusion deviceis used to talk about what used to be called the hydrogen bomb. The fusion weapon must have a fission device to create the heat necessary for fusion to occur, and it uses the fission bomb to "trigger" fusion in that light. If someone uses the term "fission bomb" in a presentation, they are not talking about the so-called hydrogen bomb or any fusion weapon - if they are using the term correctly.


Which term is used to indicate the process in which two small atomic nuclei emerge from a larger one?

nuclear fusion


Was the atomic bomb used in world war 2 a fission or a fusion bomb?

Fission.


Can Atom bomb worked by atomic fission?

Yes. Later, the Hydrogen Bomb used fission/fusion.


What type of bomb is used now to replace the atomic bomb?

First hydrogen bomb then nuclear missiles but they are never used because of the dropping of the atomic bombs on japan...


Which is most powerful a nuke an atomic bomb or a hydrogen bomb?

An H-Bomb is 1000 times stronger than an atomic bomb. Atomic explosions are based on splitting atoms and is a fission explosion or fission bomb. The Hydrogen bomb (also called H-Bomb) is a Fusion reaction where atoms are forced together. Atomic bombs were used in World War II, Hydrogen bombs have been tested, but not used in war.


Was the atomic bomb used more then twice?

after the atomic bomb was dropped on japan 2 times nuclear weapons were band from being used in war.


Which type of nuclear reaction is used in atomic bombs?

fission and in some fusion
