Enter the total kinetic energy of the neutron (eV) into the calculator to determine the Neutron velocity.

Neutron Velocity Formula

The following equation is used to calculate the Neutron Velocity.

Vn = 1.383 * 10 ^6 * SQRT( E) /100
  • Where Vn is the neutron velocity (m/s)
  • E is the neutron energy (eV)

To calculate the neutron velocity, take the square root of the neutron energy, divide by 100, then multiply by 1.383E6.

What is a Neutron Velocity?

Definition:

A neutron's velocity is the measure of the speed of a neutron based on its mass and kinetic energy.

How to Calculate Neutron Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Neutron Velocity.

First, determine the neutron energy. In this example, the neutron energy is found to be 500 eV.

Finally, calculate the Neutron Velocity using the formula above:

Vn = 1.383 * 10 ^6 * SQRT( 500) /100

Vn = 1.383 * 10 ^6 * SQRT( 500) /100

Vn = 309,248.201 m/s

FAQ

What is the significance of measuring neutron velocity?

Measuring neutron velocity is crucial in various scientific and engineering fields, including nuclear physics, reactor design, and safety analysis. It helps in understanding neutron behavior, reaction rates, and the control of nuclear reactions.

How does the energy of a neutron affect its velocity?

The velocity of a neutron is directly related to its kinetic energy. Higher energy neutrons move at higher velocities. The relationship between a neutron's energy and its velocity is described by the formula Vn = 1.383 * 10^6 * SQRT(E) / 100, where E is the neutron energy in electron volts (eV).

Can neutron velocity be measured directly?

Direct measurement of neutron velocity is challenging due to the neutrons' small size and neutral charge. However, indirect methods, such as time-of-flight measurements and the use of neutron detectors in conjunction with known neutron energy levels, can provide accurate velocity estimates.
