The measurement of the ${}^{99}$Tc $\beta$-decay spectrum and its implications for the effective value of weak axial coupling

J. W. Song, M. Ramalho, M. K. Lee +9

Measurements of $\beta$-spectral shapes is an important way to examine the effective value of the weak axial coupling $g_{\mathrm{A}}$. These stu\ dies focus specifically on forbidden non-u…
