Nuclear principles in engineering ch3

a quantum system is composed of nucleons of nearly equal mass and the same intrinsic angular momentum (spin)

one of the best ways to determine the size of a nucleus is to scatter high energy electrons from it

the density of all nuclei is equal

as the velocity of a body increases , its mass decreases

in the relativistic case, the more energy an object has , the heavier it is

the rest mass energy plus the kinetic energy of a particle are equal to its rest mass multiplied by the velocity of light squared

the greater the binding energy,the more stable the nucleus

the binding energy per nucleon does not vary with atomic mass number

nuclei that are near to the iron peak in the stability curve represent the most stable elements

heavy nuclei are more stable when they split in two

nuclei with the same number of protons but different number of neutrons are called isobars

neutron is an unstable particle unless its bound to a nucleus

the force that holds the nucleus together is called the strong force

hydrogen and deuteron have two excited states

heavier nucleus has less energy levels than the light nucleus

the liquid drop model belongs to the class of :

the binding energy of a nucleus is proportional to the number of nucleons

the surface nucleons tend to increase the total BE of a nucleus

nuclei with even numbers of protons and neutrons have higher BE

nuclei with a magic number of neutrons or protons have more stable isotopes

nuclei with the same atomic mass numbers (A) are called :

a model that describes the nucleus as a whole entity where the nucleons interact strongly together is :

in the shell model , nucleons have a large mean free path .

the semi-empirical formula can only be used to calculate the binding energy of a nucleus .
