We describe odd isotopes as formed of a core plus one neutron. We have calculated the modification of single neutron energies brought by couplings of the neutron with collective $2^+$ phonons in the cores. The results reproduce very well the inversion of $2s$ and $1d_{5/2}$ shells in...

The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
When neu- trons or protons fill a shell completely, and that shell is separated from the next by a large energy gap, the nuclei are said to have a magic number of neutrons or protons. These nuclei are extremely strongly bound. With 8 protons and 20 neutrons, the most neutron-rich oxy...
Electronic configuration is defined asthe distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number. Is the number of neutrons in oxygen 16?
Isotopes of an element a) have the same number of protons b) have the same number of neurons c) have fewer electrons than the element d) Are all radioactive The atomic number tells you the ___ for an element. a. Number of protons b. Atomic mass c. Number of neutrons ...
