Non-coherent character of isoscalar pairing probed with Gamow-Teller strength: New insight into ${}^{14}$C dating $\beta$ decay

Yutaka Utsuno, Yoshitaka Fujita

We investigate the phase coherence of isoscalar pairs from the $B(\mathrm{GT};0_1^{+}T=1\to 1_1^{+}T=0)$ values in two-particle configurations of $A=6$, 18, and 42 nuclei and…
