Summary
Muonic deuterium experiments may resolve discrepancies in muonic hydrogen 2P-2S transition energy. Deuteron polarizability effects were analyzed, yielding a deuteron structure correction of 1.680(16) meV.
Area of Science:
- Atomic Physics
- Quantum Electrodynamics
- Nuclear Physics
Background:
- The muonic hydrogen experiment measuring the 2P-2S transition energy shows significant discrepancies with quantum electrodynamics predictions.
- Muonic deuterium (μD) offers an alternative system for theoretical and experimental comparison to resolve these discrepancies.
Purpose of the Study:
- To investigate the effect of deuteron polarizability on the 2P-2S transition energy in muonic deuterium.
- To determine the deuteron structure correction for the 2P-2S transition in muonic deuterium.
Main Methods:
- Detailed theoretical investigation of deuteron polarizability effects in muonic deuterium.
- Analysis of the cancellation between polarizability and elastic contributions.
Main Results:
- The study details the impact of deuteron polarizability, finding a cancellation with the elastic contribution.

03:18Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

00:48¹H NMR of Labile Protons: Deuterium (²H) Substitution
This lesson illustrates the role of deuterium substitution in simplifying the NMR spectrum of compounds comprising labile protons. One method employed is the use of deuterium. Amongst the three isotopes of hydrogen, deuterium (2H) has a nucleus composed of one proton and one neutron. When the D2O solvent is added to a pure dry ethanol solution, its labile proton is substituted with deuterium.
02:13Nuclear Binding Energy
The difference between the calculated and experimentally measured masses is known as the mass defect of the atom. In the case of helium-4, the mass defect indicates a “loss” in mass of 4.0331 amu – 4.0026 amu = 0.0305 amu. The loss in mass accompanying the formation of an atom from protons, neutrons, and electrons is due to the conversion of that mass into energy that is evolved as the atom forms. The nuclear binding energy is the energy produced when the atoms’ nucleons are bound together;...
02:10Additional Subnuclear Structures
The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals.
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles, paraspeckles, etc. These nuclear...

00:59Atomic Nuclei: Nuclear Magnetic Moment
All atomic nuclei are positively charged. When they have a nonzero spin, they behave like rotating charges. As a consequence of their charge and spin, these nuclei generate a magnetic field (B). This, in turn, gives rise to a magnetic moment (μ), which is randomly oriented in the absence of an external magnetic field. When an external magnetic field (B0) is applied, the magnetic moment vectors can align with the field or against it in 2 + 1 orientations. A hydrogen nucleus, which is just a...
