By what interaction, anqmxpzmbw xrw+ de8:+ x31qa0/d why, dcbr8f l9 z23,wu;po r*vis0kjoes $\Sigma^0$ decay to $\Lambda^0 + \gamma$? What about $\Xi^-$ decaying to $\Lambda^0 + \pi^-$?
参考答案:
The decay times indicate that $\Sigma^+$ and $\Sigma^-$ will decay via the weak interaction (although not to $\Lambda^0$). The decay times also indicate that the $\Sigma^0$ will decay via the electromagnetic interaction (verified by the production of a gamma).
