Just want to see if I got this.

When a neutron comes into contact with a nucleus of an atom, two things (that I know of) can happen. One is that the nucleus can absorb the neutron, this typically happens in lighter atoms due to the stronger force over the smaller nucleus being able to withstand the impact and not break apart (this part I made up myself, because I think it may be true), and the nucleus absorbs the kinetic energy of the neutron. This can cause the nucleus to become unstable, due to the energy of the neutron being transferred to the nucles. This typically results in beta decay. If the nucleus is much larger, it may break apart completely, or undergo fission

There are more possibilities. The most common is elastic scattering (bouncing). Others include simple absorption (H1 becomes H2) and also other decay processes besides beta.
 
Toponium is a hadron which is the bound state of a valance top quark and a valance antitop quark. Oversimplified presentations often state that top quarks don't form hadrons, because they decay to bottom quarks extremely rapidly after they are created, leaving no time to form a hadron. And, the vast majority of the time, this is true. But, the lifetime of a top quark is only an average lifetime. Sometimes it decays faster and sometimes it decays slower. In the highly improbable case that...
I'm following this paper by Kitaev on SL(2,R) representations and I'm having a problem in the normalization of the continuous eigenfunctions (eqs. (67)-(70)), which satisfy \langle f_s | f_{s'} \rangle = \int_{0}^{1} \frac{2}{(1-u)^2} f_s(u)^* f_{s'}(u) \, du. \tag{67} The singular contribution of the integral arises at the endpoint u=1 of the integral, and in the limit u \to 1, the function f_s(u) takes on the form f_s(u) \approx a_s (1-u)^{1/2 + i s} + a_s^* (1-u)^{1/2 - i s}. \tag{70}...
