Definition : (Geo, G. the Earth; Morph, G. Form, ology G. the science of) Geomorphology is the study of landscapes--It entails the systematic description of landforms and the analysis of the processes that create them.
Nuclear binding energy is the energy that would be required to disassemble the nucleus of an atom into its component parts. These component parts are neutrons and protons, which are collectively called nucleons.
The binding energy for the last neutron is a maximum for a magic neutron number and drops sharply for the next neutron added. Electric quadrupole moments are near zero for magic number nuclei. The excitation energy from the ground nuclear state to the first excited state is greater for closed shells.
