 The neutron is a subatomic particle that has the symbol n no net electric charge and a mass slightly larger than that of a proton.  With the exception of hydrogen-1, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons.  Neutrons are necessary within an atomic nucleus, as they bind with protons via the nuclear force ; protons are unable to bind with each other because their mutual electromagnetic repulsion is stronger than the attraction of the nuclear force.  The number of neutrons determines the isotope of an element.

 The neutron has been the key to nuclear power production.  The neutron was discovered in 1932, and in 1933, it was realized that it might mediate a nuclear chain reaction .  In the 1930s, neutrons were used to produce many different types of nuclear transmutations.

 Mass  Spin  Charge  Electric dipole moment  Magnetic dipole moment  Neutron mean lifetime

 The neutron is complicated enough to be interesting, but is simple enough to be understandable  Neutron spectroscopy is a part of neutron physics studying energy dependence of effective cross sections of different neutron nuclear interactions and formed nuclei excited state characteristics.

 The element composition of our sample contained isotopes of Zinc and Copper .  Zn 67 isotope was found to be the most abundant  The sample was identified to be brass  Neutron spectroscopy is a useful and important method of identifying isotope composition of samples.

 First and foremost I wish to thank God almighty, the giver of life, for blessing me with the opportunity.  I would also like to express my appreciation to my supervisor and co-supervisors :Professor L.B. Pikelner, P .V. Sedyshev, V.N, Bazhazhina  I would also like to extend a hand of gratitude to NRF , DST , and JINR for the financial support and granting me this once in a lifetime opportunity.
