Abstract

Small-angle (π⁺, π⁻ cross sections for the 0⁺ (g.s.)→0⁺ (g.s.) transition in ββ-decay-allowed nuclei ¹²⁸Te and ¹³⁰Te were measured in the Δ₃₃ resonance region. The ratio of the cross section for ¹³⁰Te to that for $^{128} Te is 2.92±1.38$ , in opposite trend to the currently accepted $A^{−43}$ dependence of the nonanalog (π⁺, π⁻) transitions. Possible consequences on the interpretation of geochemical ββ-decay half-life ratio are discussed.

Abstract: Nuclear spectroscopic information for known nuclides of mass number 130 (Ag,Cd,In,Sn,Sb,Te,I,Xe,Cs,Ba, La,Ce,Pr,Nd,Pm,Sm) has been evaluated and presented together with adopted energies, Jp, and decay modes of levels in these nuclei. No data are yet available for excited states in ¹³⁰Ag and ¹³⁰Pm. This evaluation supersedes earlier (1989Se13,1974Hi08) Nuclear Data Sheets for A=130. In the opinion of the evaluator the decay schemes of ¹³⁰In, ¹³⁰Sn, ¹³⁰Sb and ¹³⁰Pr nuclides are not well established. The identification of ¹³⁰Ag isotope is only tentative. The ground state and possible low-lying isomer of ¹³⁰Pr are still not established in energy and Jp assignment. Search (by 1983La27) for proton decay from ¹³⁰Eu decay proved negative, thus ¹³⁰Eu isotope remains unidentified.
Pionic charge exchange in nuclei
1992, Progress in Particle and Nuclear Physics
The status of pionic single and double charge exchange reactions on nuclei is reviewed. The present data base extending from very low pion energies up to 550 MeV reveals many surprising facets of these processes. Measurements and their interpretations are discussed with the main emphasis being put on the double charge exchange reaction, its reaction mechanism, the role of nucleon-nucleon correlations and its relation to double beta decay.
Description of the ground-state pionic double charge exchange reaction on <sup>128,130</sup>Te
1991, Nuclear Physics, Section A
The pionic double change exchange reactions ^128,130Te(π⁺, π⁻)^128,130Xe are investigated within the proton-neutron random-phase approximation. The approach is fpund to give a satisfactory agreement of the calculated differential cross sections and angular distributions with recent data. A strong dependence of the calculated quantities on the strength g_pp of the particle-particle force is observed. This behaviour is similar to that reported for the β⁺ decay in neutron-dificient nuclei and the double beta decay. The role of the DCX for the interpretation of the ratio of the double beta decay half-lives of the tellurium isotopes is discussed.
