According to the shell model, nuclear energy levels, individually for neutrons and protons, are filled successively, in conformity with the Pauli exclusion principle. Just as in the atomic case, there are certain "magic numbers" in the occupancy of nucleon shells: 2, 8, 20, 28, 50, 82, and 126, which confer enhanced stability to nuclei.

Traditional nuclear physics allowed the exploration of nuclear structure close to the nuclear species that occur in nature, that is along the line of beta stability, shown in Fig. 9.2. An important motivation, mentioned in section 9.2.4 , for undertaking spectroscopic studies away from the stability line was to search for new structures: new deformed regions and new combinations of magic numbers.

Nuclear physics Not-so-magic numbers David Warner When a nucleus has a ‘magic’ number of neutrons or protons, it is particularly stable. But it seems that for exotic nuclei, with large numbers of neutrons relative to protons, these magic numbers can change. M ost people are familiar with the concept of an atom as a mini Solar With the complete filling of a nuclear shell, often referred to as " magic number," nuclei exhibit distinctive attributes that can be probed in the laboratory. For example, a large energy for the In nuclear physics, a magic number is a number of nucleons (either protons or neutrons, separately) such that they are arranged into complete shells within the atomic nucleus. As a result, atomic nuclei with a 'magic' number of protons or neutrons are much more stable than other nuclei.

Magic numbers of nucleons: nuclei with Z or N = 2, 8, 20, 28, 50, 82, 126 are extremely stable..Nuclei with Z and N magic numbers are said to be doubly magic Üe.g., 78Ni. P. Teixeira-Dias PH2510 - Atomic and Nuclear Physics Royal Holloway Univ of London Nucleon separation energies Compare ionization energies in atoms c KS Krane Figure 5.1 The simplest of the single particle models is the nuclear shell model. It is based on the observation that the nuclear mass formula, which describes the nuclear masses quite well on average, fails for certain “magic numbers”, i.e., for neutron number \(N=20,28,50,82,126\) and proton number \(Z=20,28,50,82\), as shown previously.

Introduction The evolution of nuclear physics has been strongly hampered by the poor understanding of nuclear forces. In spite of initial expectations, the nuclear force model proposed by Yukawa remained a It has its application in both nuclear physics and nuclear chemistry. This observation that there are some magic numbers of nucleons (2, 8, 20, 28, 50, 82, 126) being tightly bound in a nucleus as compared to the next higher number, gave rise to the shell model.
