Consider two hypothetical nuclei X1 and X2 undergoing β decay, resulting in nuclei Y1 and Y2, respectively. If the nuclear spin-parity transition for X1 → Y1 is 0+ → 0+ and for X2 → Y2 is 1+ → 0+, which of the following statements is correct?
- 1X1 → Y1 is a Gamow-Teller transition and X2 → Y2 is a Gamow-Teller transition
- 2X1 → Y1 is a Gamow-Teller transition and X2 → Y2 is a Fermi transition
- 3X1 → Y1 is a Fermi transition and X2 → Y2 is a Gamow-Teller transition✓
- 4X1 → Y1 is a Fermi transition and X2 → Y2 is a Fermi transition
Correct answer
X1 → Y1 is a Fermi transition and X2 → Y2 is a Gamow-Teller transition
