Abstract

The g-factors of the first-excited 2⁺ states of ^{144, 146, 148}Nd were deduced from precession measurements in which the excited nuclei recoil through (TF IMPAC) or stop in (IMPAC) magnetized iron. The transient and static hyperfine fields which are active in these cases have been calibrated. The results for the g-factors, combined with previous data which were reanalyzed in the present work, are: g₁₄₄ = 0.15 ± 0.02, g₁₄₆ = 0.25 ± 0.04, g₁₄₈ = 0.32 ± 0.04. The g-factor for ¹⁴⁴Nd, which is abnormally low for a collective 2⁺ state, cannot be accounted for theoretically.

Nuclear Data Sheets for A = 146
2016, Nuclear Data Sheets
Evaluated nuclear structure and decay data for all nuclei within the A = 146 mass chain are presented. The experimental data are evaluated and best values for level and gamma-ray energies, quantum numbers, lifetimes, gamma-ray intensities, and other nuclear properties are recommended. Inconsistencies and discrepancies that exist in the literature are noted. This work supersedes the earlier evaluation by L.K. Peker, J.K. Tuli (1997Pe22), published in Nuclear Data Sheets 82, 187 (1997).

Evidence for 2 f(7/2) neutron strength in the low energy structure of<inf>144,146,148,150</inf>Nd isotopes
2000, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
The g factors of the 4⁺₁ and 6⁺₁ states in ^144,148Nd, the 4⁺₁ state in ¹⁴⁶Nd and the 4⁺₁, 6⁺₁, 8⁺₁ and 10⁺₁ states in ¹⁵⁰Nd have been measured for the first time by projectile Coulomb excitation combined with the transient field technique. The g factors of the 2⁺₁ states in ^{144,146,148,150}Nd have been remeasured with very high precision. A pronounced transition in the structure of these isotopes occurs as neutrons are removed from the rotational ¹⁵⁰Nd and shell closure at N=82 is approached. The g factors unambiguously reflect the increasing strength of the (2f_7/2)_νⁿ configuration.

Gyromagnetic ratios in the transitional nuclei <sup>144,146,148,150</sup>Nd
1990, Nuclear Physics, Section A
The gyromagnetic rati1os of the first-excited 2⁺ levels in the even ¹⁴⁴–¹⁵⁰Nd isotopes were measured using the thin-foil transient-field technique. A marked isotopic mass dependence of the g-factors obtained can be correlated with changes in the proton and neutron pairing gaps as the deformation increases. Results are compared with and discussed in terms of theoretical calculations, including the interacting boson model.
