Density of nuclear matter cup be Estimated
Various nuclei. Ahe density of nuclear matter cup be estimated from the ratio of nuclcar ss and nuclear volume and is of the order of about 2 x 10" kg/m which extremely high. The density of some of stars like white dwarfs is also very high and is cómparable to the density of nuclear matter, oment, This is also confirmed from other static and dynamic properties 1.3 Nuclear Mass The nuclear nass had been éarlier estimated in terms of atomic mass- unit which was defined as egual to 1/16th of mass of neutral O0 isótope whose mass was taken exactly equal to 16.00.
Ho ver, International Union of Pure and Applied Physics adopted a differe, unit of mass in 1960 which was defined as thất unit of mass which is equal to 1/12th of mass. of C4 heutral isotope whose imass was taken exactly equal to 12.0000. The atomic mass.
Unit is equal to 1.66043 x 10 27 kg. The masses of all the nuclei and atoms are now expressed in terms of this atomie mass unit. The,mass of proton and neutron on this scale is 1.007277 and 1.008665 mass units, respectively, The mass of hydrogen atom, which is equal to the sum of mass of a proton and an electron, is h007825 mass units. The equivalent energy, Moc produced due to conversion of 1 atómic mass unit, (amu), is equal to 1.66 x 10:21 x (3 x 10, i.e. 1.49 x 1010 Joules or about 931 MeV. Mass spectroscopic techniques are.
