标题： Theoretical Response to the Discovery of Deeply Bound Pionic States in 208Pb(d,3He) reactions

摘要： 最近，在（d, $^3$He）反应中通过实验发现了深束缚态的π介子态存在于 $^{208}$铅核中。 他们发现在π介子产生阈值以下束缚区存在孤立的峰结构。 我们理论研究了在T$_d$=600 MeV能量下（d, $^3$He）反应中这些激发函数在 $^{208}$铅核上的行为。 我们发现与（d, $^3$He）激发函数非常吻合，并且能够识别出π介子态的潜在结构。 我们研究了（d, $^3$He）反应的能量依赖性以及随着入射能量变化的激发函数的变化。 显示英文摘要

摘要： Recently, deeply bound pionic states were found experimentally in (d, $^3$He) reactions on $^{208}$Pb. They found an isolated peak structure in the bound region below the pion production threshold. We study theoretically these excitation functions in (d, $^3$He) reactions on $^{208}$Pb at T$_d$=600 MeV. We found very good agreement with the (d, $^3$He) excitation functions and could identify the underlying structures of the pionic states. We study the energy dependence of the (d, $^3$He) reactions and the change of the excitation functions with the incident energy.
