Gamow-Teller decay of 118Pd and of the new isotope 120Pd
1993
Abstract With the use of the proton-induced fission of 238 U and the ion guide-fed on-line mass separation, even- A isotopes of palladium with high neutron excess were studied by means of γ-ray and conversion-electron spectroscopy. The decay of 118 Pd was reinvestigated in detail, and evidence for the new isotope 120 Pd, with a half-life T 1 2 = 0.5 ± 0.1 s , was found. As established for 118 Pd and tentatively shown for 120 Pd, the β-decay of these two isotopes proceeds mainly through 0 + → 1 + Gamow-Teller transitions with log ft values between 4.2 and 4.7. The strength of individual transitions has been compared with the predictions of the shell-correction model with a deformed Woods-Sax…
Beta decay of the new isotope101Sn
1995
The very neutron-deficient isotope 101Sn was produced in a 50Cr(58Ni, 2p5n) reaction and its decay properties were determined for the first time. By using chemically selective ion sources of an on-line mass separator, the energy spectrum and the half-life (3 ± 1 s) of beta-delayed protons of 101Sn were measured. These results are compared to theoretical predictions.
Gamow-Teller Beta Decay of Neutron Rich Tc, Ru, Rh and Pd Isotopes
1988
During recent experiments at the IGISOL-facility several new neutron rich nuclides have been discovered, including the first direct observations of the beta decays of 111Tc, 112Ru, 113Ru, 114Ru, 113Rh, 115Rh, 116Rh and 118Pd. The role of the νg7/2 → πg9/2 transformation in the beta decays of the odd-odd 110–116Rh and the even-even 114–118Pd isotopes is shown to be dominant. The experimental results are compared with shell model calculations including deformation and pairing.
