The experimental results from the various reaction and radioactive decay studies leading to nuclides in the A=162 mass chain, and α decays from it, have been reviewed. These data are summarized and presented, together with some model-dependent interpretation and adopted level schemes and properties.

The correlation of quadrupole transition rates of deformed nuclei by non-parametric approach
2022, Nuclear Physics A
Citation Excerpt :
The electromagnetic transition rates are the observables that are sensitive to the wavefunctions and nuclear structure. In this study, we tried to consider the correlation of these quantities independent of a special model and therefore, focused on all available experimental data [30–80]. These transition rates are pure E2-type and we don't consider some transitions which have mixing ratios with dipole magnetic (M1) and hexadecapole electric (E4) transitions.
In this study, we tried to investigate the possible correlation of inter and intra-band quadrupole transition probabilities of rotational bands. To this aim, all the available experimental values of quadrupole transition rates between different levels of the ground band together quadrupole transitions of gamma and beta bands, $2_{γ}^{+} \to 0_{g}^{+}$ and $2_{β}^{+} \to 0_{g}^{+}$ , of even-even prolate nuclei in the $150 < A < 250$ mass region are analyzed. We extended the kernel density estimation approach as a non-parametric estimation formalism for this analysis and compared its predictions with the results of the commonly used parametric technique with emphasis on Porter-Thomas distribution. The results show that the statistical correlation is dominant for such inter-band transitions between different levels of the ground band but for intra-band transitions which originated from the beta band, deviation from correlated behavior is obvious. Also, the comparison of the statistical behavior of $2^{+} \to 0^{+}$ transitions of different rotational bands, suggests the most GOE-like behavior for the quadrupole transitions between the levels of the ground band.
Complete spectroscopy of the 162Dy nucleus
2006, Nuclear Physics A
States in ¹⁶²Dy have been populated by $(n, γ)$ , $(n, e^{-})$ , and $(α, 2 n)$ reactions in order to characterize a complete set of low K bands below 2 MeV. The $(n, γ)$ and $(n, e^{-})$ measurements were made using high precision curved crystal and $β^{-}$ spectrometers. Gamma–gamma coincidence and DCO measurements were made following the $(α, 2 n)$ reaction using an array of Compton-suppressed Ge detectors. Using all these data and employing the Ritz combination principle, a level scheme was developed which represents one of the most complete and extensive spectra of levels available for comparison with nuclear models. The observed positive and negative parity bands are discussed in terms of collective quadrupole and octupole vibrational excitations as well as 2 quasi-particle excitations.

Reduced electric-octupole transition probabilities, B(E3;0<inf>1</inf>+ → 3<inf>1</inf>-) - An update
2002, Atomic Data and Nuclear Data Tables
A previous compilation of excitation energies E_x (3₁⁻) and reduced electric-octupole transition probabilities B(E3;0₁⁺→3₁⁻) for first 3⁻ states of even-even nuclides, which covered the literature to March 1988, has been updated to cover the literature to the end of 2000. Data obtained from various experimental procedures are tabulated. The final table presents adopted values of B(E3;0₁⁺→3₁⁻), together with the E3 transition strengths |M(E3)|² in Weisskopf units. Plots of |M(E3)|² versus mass number A, atomic number Z, and neutron number N confirm the existence of structure suggested in the earlier work.
General properties of the πh<inf>9/2</inf>[541]1/2- configuration and level scheme of 165Tm
2001, Nuclear Physics A
¹⁶⁵Tm has been studied through the reactions ¹⁵⁰Nd(¹⁹F, 4n), E_beam=85 MeV and ¹⁵⁴Sm (¹⁵N, 4n), E_beam=70 MeV. The level scheme has been extended to spin 71/2⁻ℏ, and four new bands have been added. Two are assigned to the K=17/2, three-quasiparticle configurations, π[523]7/2⁻⊗ν[642]5/2⁺⊗ν[523]5/2⁻ and π[404]7/2⁺⊗ν[642]5/2⁺⊗ν[523]5/2⁻, and the remaining two are assigned to γ-vibrations coupled to an h_9/2 proton. Lifetimes of high-spin states in the [541]1/2⁻ and [411]1/2⁺ bands have been measured using DSAM techniques, allowing transition quadrupole moments to be deduced. Furthermore, crossings between the [541]1/2⁻ and [523]7/2⁻ bands and between the [411]1/2⁺ and [404]7/2⁺ bands are analysed with a band-mixing calculation to obtain the quadrupole moments of the [523]7/2⁻ and [404]7/2⁺ bands. While the [523]7/2⁻, [411]1/2⁺ and [404]7/2⁺ bands all have similar deformations, the [541]1/2⁻ band has a quadrupole moment approximately 15% larger. The relative deformations are in good agreement with diabatic potential energy surface calculations performed using the code “Ultimate Cranker”. The experimental crossing frequency, due to the alignment of i_13/2 neutrons, is found to be delayed in the [541]1/2⁻ band compared to the other bands. This is a universal feature in the rare-earth region, and extensive systematic Cranked Shell Model calculations have been performed to predict deformations and crossing frequencies for nuclei in the region. The model is unable to reproduce the full delay in crossing frequency, confirming that deformation alone is not responsible for the shift.
Coulomb exchange and pairing contributions in nuclear Hartree-Fock-Bogoliubov calculations with the Gogny force
2001, Nuclear Physics A
We present exact Hartree–Fock–Bogoliubov calculations with the finite-range density-dependent Gogny force using a triaxial basis. For the first time, all contributions to the pairing and Fock fields arising from the Gogny and Coulomb interactions as well as the two-body correction of the kinetic energy have been calculated in this basis. We analyze the relevance of these terms in different regions of the periodic table at zero and high angular momentum. The validity of commonly used approximations that neglect different terms in the variational equations is also checked. We find a decrease of the proton-pairing energies mainly due to a Coulomb antipairing effect.
