kärnmagnetonen

The kärnmagneton, symbolized by $\mu_N$, is a fundamental physical constant representing the magnetic dipole moment of a proton or neutron. It is defined as $e\hbar / 2m_p$, where $e$ is the elementary charge, $\hbar$ is the reduced Planck constant, and $m_p$ is the proton mass. The value of the kärnmagneton is approximately $5.05078 \times 10^{-27}$ joules per tesla. This unit is crucial in nuclear physics and quantum mechanics for describing the magnetic properties of atomic nuclei and their constituents. The magnetic moment of a nucleon, such as a proton or neutron, is often expressed as a multiple of the kärnmagneton. While the proton has a magnetic moment slightly larger than one kärnmagneton, the neutron, despite having no net electric charge, also possesses a magnetic moment due to its internal quark structure. The concept of the kärnmagneton is analogous to the Bohr magneton, which describes the magnetic moment of electrons. Understanding the kärnmagneton is essential for interpreting experimental results related to nuclear magnetic resonance, nuclear magnetic moments, and interactions between magnetic fields and atomic nuclei.
