TL;DR: In this paper, the giant dipole resonance was interpreted as arising from the E/sub subgamma rays in the 2.10 MeV range, which were consistent with statistical-model calculations using the giant-dipole-resonance strength function.
Abstract: Spectra of ..gamma.. rays in the 2--30-MeV range have been observed following /sup 40/Ar-induced reactions leading to the /sup 122/Te, /sup 150/Gd, and /sup 164/Er systems. Shoulders in the spectra for E/sub ..gamma../>10 MeV are interpreted as arising from the giant dipole resonance and are consistent with statistical-model calculations using the giant-dipole-resonance strength function. Their observation offers the possibility of studying nuclear shapes and dynamics as functions of temperature and spin.

TL;DR: In this article, the start of a third yrast discontinuity at $I=38$ is indicated and candidates for the $I = 40$ state are suggested and possible causes of the discontinuity are discussed.
Abstract: Discrete yrast transitions from states with spins up to $I=38$ have been observed in $^{158}\mathrm{Er}$ via the reaction $^{122}\mathrm{Sn}(^{40}\mathrm{Ar}, 4n\ensuremath{\gamma})$ In addition to the pronounced backbend at $I=14$ and the upbend at $I=28$ previously known, the start of a third yrast discontinuity at $I=38$ is indicated Candidates for the $I=40$ state are suggested and possible causes of the yrast discontinuity are discussed

TL;DR: In this paper, the deexcitation of the ground state rotational band in nine deformed even nuclei has been observed following heavy-ion nuclear reactions, and the transitions from states up to spin 16 (on the average) were observed and their energies were measured with an accuracy of ± 0.3%.

Journal ArticleDOI
TL;DR: Based on the particle-plus-rotor model, it was shown that a new coupling scheme should occur in nuclei under certain conditions as discussed by the authors, in which j is quantized along the direction of I rather than along the symmetry axis.

TL;DR: In this paper, the reduced electric quadrupole transition probability, B(E2)↑, from the ground state to the first-excited 2+ state of even-even nuclides are given in Table I.
Abstract: Adopted values for the reduced electric quadrupole transition probability, B(E2)↑, from the ground state to the first-excited 2+ state of even–even nuclides are given in Table I. Values of τ, the mean life of the 2+ state; E, the energy; and β, the quadrupole deformation parameter, are also listed there. The ratio of β to the value expected from the single-particle model is presented. The intrinsic quadrupole moment, Q0, is deduced from the B(E2)↑ value. The product E×B(E2)↑ is expressed as a percentage of the energy-weighted total and isoscalar E2 sum-rule strengths. Table II presents the data on which Table I is based, namely the experimental results for B(E2)↑ values with quoted uncertainties. Information is also given on the quantity measured and the method used. The literature has been covered to November 2000. The adopted B(E2)↑ values are compared in Table III with the values given by systematics and by various theoretical models. Predictions of unmeasured B(E2)↑ values are also given in Table III.

TL;DR: In this article, the authors deal with phenomena that occur in the presence of strong electromagnetic fields, where the behavior of electrons (or positrons) under the influence of weak perturbations is considered.
Abstract: Up to now, our considerations in this book have mainly treated the behaviour of electrons (or positrons) under the influence of weak perturbations. In this chapter we want to deal with phenomena that occur in the presence of strong electromagnetic fields.1

TL;DR: In this article, the experimentally determined properties of energy levels of A = 21−44 nuclei are compiled and evaluated with emphasis on nuclear spectroscopy, and the available information on excitation energies, spins, parities, isospins, lifetimes or widths and observed decay is summarized in a master table.
