Nuclear Structure and Simple Nuclear Reactions

Nuclear Structure and Nuclear Reactions

Atomic nuclei are the essence of the visible universe. Formed in the big bang or in cataclysmic astrophysical explosions, atomic nuclei are a crucial and intriguing part of the world. The basic features of atomic nuclei were understood in terms of the nuclear shell model in the 1963 Nobel Prize winning research of Eugene Paul Wigner, Maria Goeppert-Mayer, and J. Hans de Jensen. Since then, exte...

Forging the link between nuclear reactions and nuclear structure.

A comprehensive description of all single-particle properties associated with the nucleus Ca40 is generated by employing a nonlocal dispersive optical potential capable of simultaneously reproducing all relevant data above and below the Fermi energy. The introduction of nonlocality in the absorptive potentials yields equivalent elastic differential cross sections as compared to local versions b...

Nuclear reactions and nuclear ̄ssion

1 Cross sections and reaction rates 2 Consider a thin target of thickness dx and number density of targets nt being bombarded by a beam of number density Nb moving at velocity v. Each target nucleus presents a target area 3⁄4 { if one of the bombarding particles passes within the area 3⁄4, interaction (scattering, for example) occurs, otherwise not. Now if the beam covers an area A, the fractio...

Nuclear structure and reactions with stored nuclei

The use of ion-storage rings is discussed for studies of nuclear reactions and structure, with emphasis on energetic beams of short-lived, radioactive nuclei. Aspects of internal versus external luminosity are considered as well as other issues connected with the inverse kinematics of reactions induced by a circulating beam of complex nuclei. Some of the physics motivation that is driving studi...
