Graduate Mechanism of α decay - truth about structure of nuclei

[H Tomasz Grzybowski]

α decay probably implies that heavy enough nuclei which undergo this decay, consist relatively loosely bound α particles and extra neutrons.
I haven't found any theory which views nuclei in this way.
I value truth in science, and would like to know it, also regarding stucture of nuclei
and mechanism of α decay.

Please post links to the journal articles you've been reading about your question. Thank you.

I don't know how you got that impression (see also post 2), but it is wrong.

Here is a link to a quantum mechanical theory of alpha decay: https://web.archive.org/web/2009022....uct.ac.za/courses/phy300w/np/ch1/node38.html

According to Wikipedia, the Gamow theory presented on that page dates from 1928, i.e. two years after Schrödinger published his famous equation. It's commonly seen in introductory modern physics textbooks, but it should be viewed as a historical or heuristic device. Nuclear theory has come a long way since 1928.

That's indeed true, but there is some truth in Gamov's model since $\alpha$'s are pretty strongly bound beasts and thus many nuclei show some clustering of $\alpha$'s, and Gamov's model understanding $\alpha$ decay as tunneling of such "preformed" $\alpha$'s is a nice qualitative picture of the process. To be quantitative you have to use more realistic models of nuclear structure, of course.

So it looks like we should believe inexistence of nuclear null oscllations. Can the energy of these oscillations be calculated
using Planck constant h = 6.6267⋅10^-34 J⋅s ?

What are nuclear null oscillations? Which book on nuclear physics are you reading? A good one is

[H Tomasz Grzybowski]

I theorize myself. It seems natural to think that there are some oscillations which after some time lead to α decay.
And it looks like these oscillatons are incessant. So it invokes the idea of null oscilations.

It is against our rules to discuss personal theories. Additionally, the question

What are nuclear null oscillations? Which book on nuclear physics are you reading?

is still unanswered.

If you can quote a paper or textbook which you refer to, please let me know via PM.
