标题： Account of Nuclear Scattering at Volume Reflection

摘要： 对于在体积反射区域穿过弯曲晶体的粒子，我们评估其与原子核相互作用的概率。 无论连续势的形状如何，此概率被发现与非晶靶中的相应值不同，差异与晶体弯曲半径和粒子偏转角度成比例。 基于此结果，我们评估了非弹性核相互作用的速率，以及由于多次库仑散射引起的最终束流角分散。 理论预测与实验进行了比较。 还讨论了多次库仑散射对平均体积反射角的影响。 显示英文摘要

摘要： For a particle traversing a bent crystal in the regime of volume reflection we evaluate the probability of interaction with atomic nuclei. Regardless of the continuous potential shape, this probability is found to differ from the corresponding value in an amorphous target by an amount proportional to the crystal bending radius, and the particle deflection angle. Based on this result, we evaluate the rate of inelastic nuclear interactions, and the final beam angular dispersion due to multiple Coulomb scattering. The theoretical predictions are compared with the experiments. The impact of multiple Coulomb scattering on the mean volume reflection angle is also discussed.
