چکیده

New calculations are presented for Gamow-Teller beta decay of nuclei near 'Sn. Essentially all of the Sn Gamow-Teller decay strength is predicted to go to a single state at an excitation energy of 1.8 MeV in In. The first calculations are presented for the decays of neighboring odd-even and odd-odd nuclei which show, in contrast to ' Sn, surprisingly complex and broad Gamow-Teller strength distributions. The results are compared to existing experimental data and the resulting hindrance factors are discussed.

Gamow-teller Strength Distribution in the -decay of Exotic Nuclei

We describe experimental results on the Gamow-Teller strength distribution as obtained from the B-decay of exotic nuclei. The most complete results, in light nuclei, confirm the absence of strength noted in (p,n) measurements. In heavier nuclei it is the remote tail of the resonance that is established by 8-decay.

Determination of the Gamow–Teller strength function for the neutron-deficient isotopes

The Gamow–Teller β decays of the neutron-deficient indium isotopes 104–107In have been investigated by using total absorption γ -ray spectrometry on mass-separated sources. The experimental Gamow–Teller strength, deduced as a function of the excitation energy in the daughter nuclei 104–107Cd, is compared to shell-model predictions.  2001 Elsevier Science B.V.

β+ Gamow-Teller transition strengths from 46Ti and stellar electron-capture rates.

The Gamow-Teller strength in the β(+) direction to (46)Sc was extracted via the (46)Ti(t,(3)He + γ) reaction at 115  MeV/u. The γ-ray coincidences served to precisely measure the very weak Gamow-Teller transition to a final state at 991 keV. Although this transition is weak, it is crucial for accurately estimating electron-capture rates in astrophysical scenarios with relatively low stellar den...
