论文摘要
辐射的巴属衰变$ \ MATHCAL {b}^{*} \ left（\ frac {3} {2} {2} \ right）\ to \ Mathcal {b} \ left（\ frac {1} {2} {2} {2} {2} \ right）+γ$是一种磁性dipole $（M1）$（M1）$（M1）$（M1）$。它需要过渡磁矩$μ_ {\ Mathcal {b} \ left（3/2 \ right）\ to \ Mathcal {b} \ left（1/2 \ right）} $。在组成夸克模型的框架工作中评估了漏洞$ 1/2 $和$ 3/2 $的过渡磁矩，其中内在的旋转和Quarks $ u，d $和$ s $的磁矩发挥着关键作用。在此框架内，辐射延迟$δ^{+} \ to p+γ$，$σ^{*0} \toλ+γ$，$σ^{*+} \ toσ^{+}+}+γ$和$γ$和$ξ^$和$ξ^{*0} {*0} \ to to to to to n} in nate}+deats+lidet。发现这些衰减的分支比与相应的实验值非常吻合。
The radiative baryonic decay $\mathcal{B}^{*}\left(\frac{3}{2}\right)\to\mathcal{B}\left(\frac{1}{2}\right)+γ$ is a magnetic dipole $(M1)$ transition. It requires the transition magnetic moment $μ_{\mathcal{B}\left(3/2\right)\to\mathcal{B}\left(1/2\right)}$. The transition magnetic moments for the helicities $1/2$ and $3/2$ are evaluated in the frame work of constituent quark model in which the intrinsic spin and the magnetic moments of quarks $u,d$ and $s$ play a key role. Within this framework, the radiative decays $Δ^{+}\to p +γ$, $Σ^{*0}\to Λ+γ$, $Σ^{*+}\to Σ^{+}+γ$ and $Ξ^{*0}\to Ξ^{0}+γ$ are analyzed in detail. The branching ratio for these decays is found to be in good agreement with the corresponding experimental values.
