Why are only some particles fissionable/fissile?

[Vanadium 50]

you got 2 8 18 32 50 right but it stops there and starts over. the next would be 52 then 58 68 82 100

So you've got 4 right with your numerology, 4 wrong, and miss 3. I don't find that particularly impressive.

but when my ideas are being so totally misrepresented what can I do?

You could restrict your answers to mainstream physics and not bring your pet theories into it.

Uranium does not split in half when it fissions. The fission products have a spectra which correspond to two peaks, e.g. Ce-133 and Tc-99.

But spontanous fission rate of Uranium is still very low compared to its other decay modes. So one has to specify I guess, so OP understands the entire picture.

It is also ambigous what the OP means by "Why are only some particles fissionable/fissile" but I suggest he is referring to why only some nuclei can be used in fission power plants - not why some nuclei undergo spontaneous fission.

Now if you bring up your own pet theories again, here or in superconductivity, you will run into trouble. Why can't you accept and follow the rules of this forum? If not, then why are you here?

Would you, when presenting your results in an article, say "nature occasionally has exceptions"? Totally non-serious...

I still believe it is more illuminating to consider alpha decay as simply a form of spontaneous fission. The underlying physics is the same - you just have a very asymmetric split. Many nuclei only have this mode, some, like U-235, have others.

here is a surprising result I just found. I used inverse 10th power but as you can see the reasoning would work just as well with any other law including logarithmic.
