One choice for a standard of length is the Bohr radius.

This outer electron should be at nearly one Bohr radius from the nucleus.

(It is not exactly the Bohr radius due to the reduced mass effect.

The electron is most likely to be found at a distance from the nucleus equal to the Bohr radius.

Here denotes the positions of the nuclei, their atomic number and is the Bohr radius.

The Bohr radius is the radius of the smallest allowed orbit.

This means that the innermost electrons orbit at approximately 1/4 the Bohr radius.

The unit length is the Bohr radius.

The Bohr radius is related to the Compton wavelength by:

The Bohr radius including the effect of reduced mass in the hydrogen atom can be given by the following equation:

Although the model itself is now obsolete, the Bohr radius for the hydrogen atom is still regarded as an important physical constant.

Essentially the electron orbits the donor ion within the semiconductor material at approximately the bohr radius.

Its Bohr radius and ionization energy are within 0.5% of hydrogen, deuterium, and tritium.

The smallest possible value of r in the hydrogen atom is called the Bohr radius and is equal to:

The equation must be modified based on the system's Bohr radius; emissions will be of a similar character but at a different range of energies.

Nanoparticles with size near their Bohr radius can generate two excitons when struck by a sufficiently energetic photon.

Atomic unit of length (Bohr radius):

This parameter is normally reported in atomic units, i.e., in units of the Bohr radius.

The Bohr radius is built from the electron mass , Planck's constant and the electron charge .

In a semiconductor crystallite whose diameter is smaller than the size of its exciton Bohr radius, the excitons are squeezed, leading to quantum confinement.

When the size of the semiconductor crystal is smaller than the Exciton Bohr radius, the Coulomb interaction must be modified to fit the situation.

Mott argued that the transition must be sudden, occurring when the density of free electrons N and the Bohr radius satisfies .

This is done for convenience: the Bohr radius as defined above appears in equations relating to atoms other than hydrogen, where the reduced mass correction is different.

The Bohr radius is a physical constant, approximately equal to the most probable distance between the proton and electron in a hydrogen atom in its ground state.

The simplest atom, hydrogen, only has one electron, and its smallest possible orbit, that with the lowest energy, is at a distance from the nucleus called the Bohr radius.
