You can have an elasticscatteringcollision where the neutron just essentially bounces off the uranium 235 atom and just continues on and it's possibly slowed down ever so slightly.
你可以得到一个弹性散射的碰撞,在那,原子就会反射,铀235原子,还会继续,那也可能会减慢一点。

The charge exchange and elasticcollision between ion and neutral atoms and the collection and Coulomb scattering of ion on dust grains are considered.
This paper introduce a program of the "elasticcollision" experiment which is an analog of two kinds of the scattering angles and the relation between them in elasticcollision of two dimensions.
