Stripping reaction
Encyclopedia
A stripping reaction is a term used to describe two separate physical processes:
  • In nuclear physics
    Nuclear physics
    Nuclear physics is the field of physics that studies the building blocks and interactions of atomic nuclei. The most commonly known applications of nuclear physics are nuclear power generation and nuclear weapons technology, but the research has provided application in many fields, including those...

     a stripping reaction is a nuclear reaction
    Nuclear reaction
    In nuclear physics and nuclear chemistry, a nuclear reaction is semantically considered to be the process in which two nuclei, or else a nucleus of an atom and a subatomic particle from outside the atom, collide to produce products different from the initial particles...

     in which part of the incident
    Incident
    Incident may refer to:* A property of a graph *Incident , a cultural festival of The National Institute of Technology in Surathkal, Karnataka, India...

     nucleus
    Atomic nucleus
    The nucleus is the very dense region consisting of protons and neutrons at the center of an atom. It was discovered in 1911, as a result of Ernest Rutherford's interpretation of the famous 1909 Rutherford experiment performed by Hans Geiger and Ernest Marsden, under the direction of Rutherford. The...

     combines with the target nucleus, and the remainder proceeds with most of its original momentum in almost its original direction. This reaction was first described by Stuart Thomas Butler
    Stuart Thomas Butler
    Stuart Thomas Butler was an Australian nuclear physicist who served as Director of the Australian Atomic Energy Commission from 1977 until 1982, and was noted for his contributions to theoretical physics including stripping reactions, energy loss of particles in a plasma and atmospheric tides...

     in 1950. Deuteron stripping reactions have been extensively used to study nuclear reactions and structure, this occurs where the incident nucleus is a deuteron and only a proton
    Proton
    The proton is a subatomic particle with the symbol or and a positive electric charge of 1 elementary charge. One or more protons are present in the nucleus of each atom, along with neutrons. The number of protons in each atom is its atomic number....

     emerges from the target nucleus. A simple one-step stripping reaction can be represented as
A+a →B+b
A + (b+x)a→(A+x)b+b
where A represents the target core, b represents the projectile core, and x is the transferred mass which may represent any number of particles.

  • In chemistry
    Chemistry
    Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Chemistry is concerned with atoms and their interactions with other atoms, and particularly with the properties of chemical bonds....

     a stripping reaction is a chemical process, studied in a molecular beam
    Molecular beam
    A molecular beam is produced by allowing a gas at higher pressure to expand through a small orifice into a chamber at lower pressure to form a beam of particles moving at approximately equal velocities, with very few collisions between the particles...

    , in which the reaction products are scattered forward with respect to the moving centre of mass of the system.
