In stars with masses comparable to the sun, the nucleus stops collapsing only when the inner temperature reaches above 100 million degrees, the threshold temperature necessary to start up nuclear fusions again. This time helium atoms fuse with carbon atoms releasing the necessary energy to regain th ...

... A large nucleus (A 200 ) splits into two. The daughter fragments have higher binding energy than the parent. They are more stable. It was found (in 1939) that if uranium was bombarded with neutrons (these have no charge and are not repelled by the nuclei), that a uranium nucleus could be split into ...
