The nuclear structure is based mainly on measurement of the specific nuclides properties and hence the collective models of nuclei are derived from tracing the disappearance of shell effect and the beginning of deformation of isotope series.

Carbon-14 is a radioactive isotope used to date organic material.

Since the individual isotope properties differ the understanding part of many key nuclear science studies as the understanding part of many systematic studies of the nuclei depend upon the function of neutron and proton number.

This is found to be true for nuclear structure as well as nuclear reaction research.

Carbon 14 dating is a process in which the ratio of carbon 14 present in a fossil is compared with the carbon 14 present in atmosphere.

By this method we could determine the isotopic matter yet to decay in the specimen.

Once we could determine the amount, the age of the fossilised specimen could be determined.

Using carbon 14 is possible only if the specimen is less than 50 thousand years old.

Conversion of this unstable form into a more relatively stable form after going through decay process is known as its half-life.This is created when nitrogen gets an extra neutron in its nucleus and loses one proton in presence of the cosmic rays.Since the process is a continuous one so we get to see carbon 14 presence all through in atmosphere.The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes.Levels of C can represent either mixtures of modern and dead carbon or carbon that was fixed from the atmosphere less than 50,000 years ago.
