The energy that holds a nucleus together. This is equal to the mass defect of the nucleus.
〔物理〕结合能
Example sentencesExamples
It's not until you get into the elements heavier than lead (all of which are radioactive) that you find nuclei whose binding energy per nucleon is low enough that the fission fragments could tunnel apart.
The object must have greater energy than its gravitational binding energy to escape the earth's gravitational field.
A nucleus with low binding energy and low mass may reconfigure with other structures of low stability to form a more massive and stable structure through the process of nuclear fusion.
This property allows the lambda to take up no space and to slide into the center of a nucleus, where its strong binding energy pulls the other nucleons closer together.
Hence, the holding together of protons and neutrons in a nucleus can also be explained by the concept of binding energy and mass defect.
