astrophysical S-factor equation error (it had the wrong units) and also sign error since eta ~ 1/(relative incident velocity), also a typo.

fixed mathematical formatting: exp is typeset upright, and formula for S(E) is now centered/displaystyle

| Apr 28, 2017 at 20:01 | comment | added | Maury Markowitz | Ok I think I get this. This also helps explain other texts I've read about resonances that didn't really explain what they meant. So in this case when the D-T gets close enough together it sort of thinks its a single He5 instead of two separate things, as long as the energy is thus. But in T-T the energy level where they see themselves as a single thing is much higher? And that's possible BECAUSE its unstable and thus has a wide resonance. | |

The "resonance" - every energy level has some width, it is never "discrete" value unless it lives forever (Heisenberg relations). If the level is already unbound, it is usually quite wide, it could be even MeVs, this one is 74.5 keV. At any small kinetic energy, the particles feel, they are inside. How much they feel at different energies - look at the bump in S-factor picture. | |
| Apr 28, 2017 at 18:55 | comment | added | Maury Markowitz | So I'm trying to parse this. It seems the "trick" here is that there is an energy level in He5 that just happens to be lower than in He6? I'm not sure I fully understand resonances in this context. | |
