Direct nuclear reactions



Direct nuclear reactions

The spontaneous disintegration of long-lived, naturally occurring isotopes
provides one source of information on nuclei. However, only a limited number of
nuclei are accessible for study by this natural process and then only under a
narrow range of circumstances. On the other hand, nuclear reactigns can be
induced in the myriad of pairwise combinations provided by stable or long-lived
nuclei and over the wide range of energies provided by the accelerators in the
physics laboratories of the world. Reactions therefore provide the greatest
volume and widest range of nuclear data. The energy loss of a beam particle can
be directly interpreted as an excitation energy in the target nucleus. Usually,
however, the data acquire meaning for the structure of nuclei only after they have
been interpreted through a reaction theory. The synthesis of such accumulated
information into a coherent theory of the nucleus is the main subject of nuclear
physics. There are a number of volumes on nuclear structure that review this
ongoing process.
