在准自由单核子敲除反应中，什么样的密度可以被有效探测？
What densities can be effectively probed in quasifree single-nucleon knockout reactions?
摘要：
我们解决的问题是否准自由单核子敲除测量进行足够的信息核内部。为此，我们提出的反应概率密度的比较$A(e,e'p)$和$A(p,2p)$在准自由运动学的靶核$^{4}$ He，$^{12}$ C，$^{56}$ Fe，和$^{208}$ Pb。我们采用了一个全面的框架的基础上的脉冲近似和相对化扩展的Glauber多重散射反应理论，在该理论中，介质的影响有关的短程相关性（SRC）的实施。结果表明，SRC削弱了衰减的影响。对于轻靶核，准自由$(p,2p)$和$(e,e'p)$都能探测到与核饱和密度$ρ_{0}$相同量级的平均密度。对于像$^{208}$ Pb这样的重核，探测到的平均密度小于$0.1ρ_{0}$，并且$(e,e'p)$反应在探测体区方面比$(p,2p)$有效得多。
英文摘要：
We address the issue whether quasifree single-nucleon knockout measurements carry sufficient information about the nuclear interior. To this end, we present comparisons of the reaction probability densities for $A(e,e'p)$ and $A(p,2p)$ in quasifree kinematics for the target nuclei $^{4}$He, $^{12}$C, $^{56}$Fe, and $^{208}$Pb. We adopt a comprehensive framework based on the impulse approximation and on a relativized extension of Glauber multiple-scattering reaction theory in which the medium effects related to short-range correlations (SRC) are implemented. It is demonstrated that SRC weaken the effect of attenuation. For light target nuclei, both the quasifree $(p,2p)$ and $(e,e'p)$ can probe average densities of the same order as nuclear saturation density $ρ_{0}$. For heavy nuclei like $^{208}$Pb, the probed average densities are smaller than $0.1ρ_{0}$ and the $(e,e'p)$ reaction is far more efficient in probing the bulk regions than $(p,2p)$.
