What is optical model in nuclear physics?
optical model, in physics, description of atomic nuclei as similar to cloudy crystal balls in that, when struck by a beam of particles, they partially absorb the beam, partially scatter it, and partially transmit it in a way analogous to the behaviour of light.
What is optical potential?
The "optical potential" is just a model to include in your potential not only the elastic scattering (such as nuclear scattering or Coulomb scattering), but also inelastic scattering. … In this particular case, also known as the "optical model", what you do is taking from optics the concept of complex refractive index.
What are the drawbacks of liquid-drop model?
It does not explain the high stability of nuclei with the magic number. The concept of pairing cannot be explained with this model. The discontinuities in B / E nucleon cannot be explained. It is not successful in interpreting the breaking of nuclei in lighter elements.
What is liquid-drop model of nucleus?
liquid-drop model, in nuclear physics, a description of atomic nuclei in which the nucleons (neutrons and protons) behave like the molecules in a drop of liquid. … Although inadequate to explain all nuclear phenomena, the theory underlying the model provides excellent estimates of average properties of nuclei.
What is compound nuclear reaction?
The compound nucleus is the intermediate state formed in a compound nucleus reaction. It is normally one of the excited states of the nucleus formed by the combination of the incident particle and target nucleus.
What are the salient features of liquid drop model?
The Liquid Drop Model treats the nucleus as a liquid. Nuclear properties, such as the binding energy, are described in terms of volume energy, surface energy, compressibility, etc. –parameters that are usually associated with a liquid.
What are the merits and limitations of liquid drop model?
It is a crude model. It does not explain all the properties of the nucleus. 2. It does not explain the high stability of nuclei with the magic number.
