very nice but you can ask your friend feuerbacher
and he can testify that all those elements that you mentioned above are

a *family* from the nuclear structure point of view!in my model!

just a preemptive remark to Mike:
i am sure that the only motivation that drives you into this thread
is to hepl me .......... (:-)

again very nice
yet i sayed nothing aginst such posibility
i sayed that Pt cannot become Gold (the real gold only may be
an 'imposter' of Gold
---------------

  Nothing I can see decays into
> Ir-197. Hg-201 could theoretically alpha decay into Pt-197,
theorethically ??? acording to whose theory?

now we are not dealing with data that is 'tentative'
we are looking for concteet expermentally verified data
got it ???
we are loaded with tentative speculations that lead us
just to confusion. and no realadvance.

that is as well not news to me
i can even explain it with mu model and tell whichj once
have a better chance to alpha decay
it is in thise cases of which there is a single alpha particle
'dangling' catileverly at trhe edge (pole) of the nuc.
most of alpha particles in the inner structure are
'locked in the very srtong 'rectangula pipe' in which each of them
(if you have some 3d immagination) are connected with much more than
just one connection
the a;pha if you done mind is a tetraheder with 4 free edges
and here again the longish shpae of the nucleid works much better
than a 'sphere' you get sory of a 3d cross.
(acording to feuerbachers undestandings
'there is no such animal' with a very dsitinct structure
'acording to the HUP !! and he is an expert of using that
principle...._)

 Bi-209, for example.

Mike you have a very creative immagination
but my emphasis is on ..... *immagination* got it ?

btw is it reasonable that Hg will turn to be Pt
bypassing Au and only after becoming Pt will go back to Au???

acording to me Hg cannot transform to Pt!
just ask your common friend Feuerbacher
whether acording to my model
there is any tangible difernce between the skeleton of Pt
and Au

and a second question to him :
if that difference exists between Hg and Gold ?

if he does not ansew that will be an answer as well!.....
it will be another prove that he is a personal enemy of mine.

thank you mike for your efforts.(to help me )
