Abstract

Measurements have been made of the (d, p) reactions from ¹³⁸Ba, ¹⁴⁰Ce and ^{142, 144, 146}Nd to several states in the residual nuclei at a deuteron bombarding energy of 12 MeV. A method is described to extract from (d, d₀), (p, p₀) and (p, n) data, optical-model parameters with errors reflecting the experimental uncertainties. Proton parameters are obtained from optical-model fits of the (p, p₀) excitation functions for ¹³⁸Ba, ¹⁴⁰Ce, ¹⁴⁴Sm and ^{142, 144, 146}Nd in the energy range from 8.6 to 12 MeV at various scattering angles. Smoothly energy and mass dependent proton potentials were obtained with a real potential depth $V = (50+0.4 Z/A 13 +32.4(N–Z)/ A−0.4 E_{p})±3.1[MeV]$ . The (d, p) data are well reproduced and the spectroscopic factors with uncertainties are extracted using the DWBA.

Nuclear Data Sheets for A=141
2023, Nuclear Data Sheets
The experimental results published before August 2022 from the various reaction and decay studies leading to nuclides of Z=51 to Z=67, ¹⁴¹Sb, ¹⁴¹Te, ¹⁴¹I, ¹⁴¹Xe, ¹⁴¹Cs, ¹⁴¹Ba, ¹⁴¹La, ¹⁴¹Ce, ¹⁴¹Pr, ¹⁴¹Nd, ¹⁴¹Pm, ¹⁴¹Sm, ¹⁴¹Eu, ¹⁴¹Gd, ¹⁴¹Tb, ¹⁴¹Dy, ¹⁴¹Ho in the A=141 mass chain have been reviewed and the data are presented together with adopted level schemes and properties. This work supersedes the previous evaluation of the A=141 nuclides by published by N. Nica in Nuclear Data Sheets 122, 1 (2014).
Nuclear Data Sheets for A = 139
2016, Nuclear Data Sheets
The experimental nuclear spectroscopic data for known nuclides of mass number 139 (Sn, Sb, Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy) have been evaluated and presented together with adopted properties for levels and gamma rays. This evaluation represents a revision of previous one (2001Bu16) by T.W. Burrows. Since then extensive new data have become available for many A=139 nuclides although, no excited state data are yet available for ¹³⁹Sn, ¹³⁹Sb, ¹³⁹Tb, and ¹³⁹Dy. The decay schemes of ¹³⁹Sn, ¹³⁹Sb, ¹³⁹I, ¹³⁹Tb and ¹³⁹Dy nuclei are not known, and those for ¹³⁹Gd and ¹³⁹Eu are poorly known. Particle-transfer data are available for ¹³⁹Ba, ¹³⁹La, ¹³⁹Ce and ¹³⁹Pr. Limited high-spin data are available for ¹³⁹Te, ¹³⁹I, ¹³⁹Cs, ¹³⁹Ba, ¹³⁹La and ¹³⁹Ce, while such data are extensive for ¹³⁹Pr, ¹³⁹Nd, ¹³⁹Pm, ¹³⁹Sm, ¹³⁹Eu and ¹³⁹Gd. Recent ¹³⁹Pm high-spin data from two independent studies using the same reaction and similar beam energy are in conflict and could be improved using state-of-the-art large gamma-detector arrays in contrast to the smaller arrays currently used. Cases for which no new experimental information are available since the last update have undergone checking resulting in some changes in the current work, but for the most part these are taken from the previous evaluations. Thus, the present work has greatly benefited from all prior NDS evaluations (2001Bu16, 1989Bu12, 1981Pe04, 1974Gr46), but at the same time data presented herein supersede those in the earlier evaluations.
