In this work we investigate whether it is feasible with proton inelastic scattering in inverse kinematics to quantify breakup decay rates, by observing the proton recoil in a full kinematics approach. Taking as example the 2.43 MeV excited state of ⁹Be, we perform an exclusive breakup measurement of ⁹Be incident on a proton target at an energy of 51 MeV. Two of the three cluster constituents (α and α) as well as the proton target recoil are recorded in a triple coincidence mode. As in other methods we have determined relative $\alpha -\alpha$ and $\alpha -n$, Q-value and ⁹Be excitation spectra, energy spectra for all fragments observed and non observed, reconstructed in a full kinematics approach. Additionally to that, we have obtained and concentrated on energy spectra of the proton recoil. The signature of the ⁹Be configurations were identified in bi-dimensional $\mathrm{\Delta }E-E$ spectra (proton contour) and decay rates were determined for all three configurations ${}^5\text{He}+\alpha$, ${}^8\text{Be}+n$ and $\alpha +\alpha +n$. Finally a breakup cross section was deduced as ${\sigma }_{break}=(142\pm 20)\text{mb}$. We conclude that proton inelastic excitation to continuum of Borromean light nuclei in inverse kinematics, may provide the mean for probing in the proton recoil spectra the decay rates through all cluster configurations. This involves extensive simulations with the implementation of the experimental conditions and of calculations describing the physics in continuum.

在这项工作中，我们通过在完整的运动学方法中观察质子的后坐力，来研究在逆运动学中使用质子非弹性散射来量化分解衰减率是否可行。以⁹ Be的2.43 MeV激发态为例，我们以⁹ MeV的能量对质子靶上的⁹ Be进行了唯一的破裂测量。以三重合模式记录了三个簇成分中的两个（α和α）以及质子目标反冲。与其他方法一样，我们确定了相对$\alpha -\alpha$ 和 $\alpha -ñ$，Q值和⁹ Be激发光谱，观察到和未观察到的所有碎片的能谱，均以完整的运动学方法重建。除此之外，我们已经获得并专注于质子反冲的能谱。该签名^9个铍配置在两维鉴定$\mathrm{\Delta }Ë-Ë$ 确定所有三种配置的光谱（质子轮廓）和衰减率 ${}^5\text{他}+\alpha$， ${}^8\text{是}+ñ$ 和 $\alpha +\alpha +ñ$。最终推导了分手截面${\sigma }_{b\mathrm{[R}Ë\mathrm{一个}ķ}=（142\pm 20）\text{兆字节}$。我们得出结论，在逆运动学中质子非弹性激发到Borromean轻核的连续谱，可能为在质子反冲谱中探测所有团簇构型的衰减率提供平均值。这涉及到广泛的模拟，包括实验条件的实现和连续描述物理的计算。
