| 31. | The team studied the nuclear fusion reaction between uranium ions and a target of natural nickel:
|
| 32. | Billions of them, produced by fusion reactions within the Sun, fly through every person every second.
|
| 33. | In experiments last year, the Sandia researchers first detected telltale neutrons produced by the fusion reactions.
|
| 34. | With a branching probability relative to the primary fusion reaction of about 10 " 4.
|
| 35. | Other fusion reactions produce much less energetic neutrons.
|
| 36. | In that case, alien technology triggers a fusion reaction in the planet, which is largely hydrogen.
|
| 37. | The fusion reaction rate increases rapidly with temperature until it maximizes and then gradually drops off.
|
| 38. | The detonation of this " spark plug " would help to initiate and enhance the fusion reaction.
|
| 39. | To reach net power, fusion reactions have to occur fast enough to make up for energy losses.
|
| 40. | The fusion reaction also released energy, but only 10 millionths of the energy consumed by the laser.
