The discussion centers on the relationship between reaction Q value and threshold energy in calculating the energy of a reaction's ejectile. It is established that when the Q value is negative, the threshold energy must be considered in the calculations. If the energy of the incoming particles exceeds the threshold energy, the energy of the incoming particle becomes the primary factor in the calculations, while the negative Q value remains relevant. Both the threshold energy and Q value play critical roles in determining the energy of the ejectile.
PREREQUISITESStudents and professionals in nuclear physics, particle physicists, and anyone involved in calculating reaction energies and understanding the dynamics of nuclear reactions.
Both are relevant.oksuz_ said:then we should consider the energy of the particle, not the threshold energy, should not we?
That is very closely linked to the threshold energy.oksuz_ said:And also Q-value enters the calculations, but it is, in this circumstances, negative.
