But didn't we said that there should be infinite M points, not only 2? MAybe the graphic want to say that the kinetic energy of the electrons is not constant?

Yes there are infinite many values for the energy!

But it was your counlcusion made in post #67 i reacted on.

The ultimate thing the graph wants to point out is that all the electrons are not emitted with the same energy, but the energy spans over a range. This is typical for a 3body decay - there are infinite number of combinate conservation of momentum and energy when you have more than 2 bodies in the final state.

You first question was about these M1 and M2, and that question has been answered severel times in this thread, each y-value have two corresponding x values, except y_max.

The Graphic is totaly correct.

Yes, we said that there are 2 corresponding values. But also we said that it can have 3,4,5,6,8,9,10000,10010.... values for the kinetic energy of electrons...

malawi_glenn

So where is the graph not correct according to you?

Physicsissuef

I said it is correct... But having 2 points is not totally correct... It may confuse you, like in my case... I was confused why only 2 points, but later, thanks to you and Astronuc I understand that, actually there are infinite points (for each radionucleus, corresponding point, some points also may be same)...

malawi_glenn

Post #66 and 67 you say that is not correct, and only partly correct.

But anyway, I hope you have learned a bit how distribution functions work
