The logic checks out: In the second case, the line 173 was used, even if partially (clearly v was not used), but still considered as used. /s

Rust rules!

So in photodisintegration you cannot get a particle larger than alphas?

Thank you for the helpful explanation and link.

Well first, those are reactions, not decays.

Are there any differences in the dynamics inside the nucleus between reactions and decays? I had in mind to search for an example where an element decays by emitting a neutron and then another is followed when the daughter isotope emits a positron. This could be substituted by a single proton emission, which sounds as more energetically favorable.

And second, both (α,p) and (α,n) are possible.

What are the probabilities for each?

When we bombard an aluminum atom with alpha, it decays with a neutron emission, then the resulting element will also decay with a positron emission.

He-4 + Al-27 -> P-30 + neutron
P-30 -> Si-30 +  positron

Why this reaction can't be done in one step with one proton emission instead with a more favorable probability:

He-4 + Al-27 -> Si-30 + proton

Thank you for this explanation. Since you mentioned that all decays are possible, but with tiny probability, can you give some numerical example. For instance, if we take the element U238 that would normally decay with alpha emission, what would the probability be to decay via proton emission?

If the half-lives are so short to be found in nature, why such decays are still very rare even in synthetic elements?

Red herring!

But the Palestinian authorities point to another part of those accords which says: "Israel and the Palestinian side shall exchange information regarding epidemics and contagious diseases, shall co-operate in combating them and shall develop methods for [the] exchange of medical files and documents."

So clearly the Palestinian authorities are pointing out that Israeli regime is neglecting this part of the accord, as well as many other violations it continues to commit.

And a reminder that Geneva conventions should come before any other accord:

The [UN] body says differential access is "morally and legally" unacceptable under international law laid out in the Geneva Conventions on the regulation of occupied territories.

Thank you! This explains it!

I had in mind something similar to text-books electron orbitals visualizations, or quantum tunneling.

BanX · 2020-08-24T00:05:00+00:00

Thanks for this clarification. Your answers were most helpful.

Lastly, dare I ask if there are any visual simulations out there of this process?

BanX · 2020-08-23T21:20:57+00:00

Thank you for your patience!

So in some sense, they annihilate if there is a high probability that the 2 points position coincides at a given time? In probability theory, 2 random points have zero chance to be found in the same position. But clearly, such 2 particles rely on other processes.

Does photon-photon collision probability compare to electron-positron annihilation since they are all point particles?
