Nuclear Orientation

Dynamic Orientation of Nuclei

“…At present they are the only successful methods for polarized proton and deuteron targets; besides, they have a strong appeal to the solid state physicist inter ested in the general problem of spin-spin-phonon dynamics in solids. We note other reviews (6,9,32,(43)(44)(45)(46)(47), as well as a recent monograph (48) giving fuller details on solid state aspects.…”

“…Another static method utilizes the nuclear electric quadrupole interaction with the crystal field (19). Since detailed discussions are given in earlier articles (1,(5)(6)(7)(8)(9)(10), we merely present Table I, listing all nuclei which have been oriented by static methods. Most of the experiments involve neutron scatter ing or angular distribution of a, {3, and 'Y rays, and yield information on de cay schemes, spins of excited states, {3-decay matrix elements, and parity non conservation.…”

“…. (1,(5)(6)(7)(8)(9)(10) The use of a magnetic field to polarize nuclei is the classic example of static orientation: one simply cools the sample, provides an interaction JC, constant in time, and waits for thermal equilibrium. The problem, of course, is to make JC"2:,kT.…”

14 Particle Decay Study of Oriented Nuclei

“…First angular distributions of fission fragments, together with the α-particle anisotropics, were measured by Dabbs etal. on 233 U and 235 U using the thermal neutron beam of the Oak Ridge graphite reactor [83]. Neutron energies between 0.1 and 10 eV were used.…”

Application of Atomic Beams to Elementary-Particle and Nuclear Physics

“…19 We chose Ne for this study because of the relative ease of production of a polarized beam (1. 8,19), and because of its large decay matrix elements:…”
