Title: What are the nuclear properties of different isotopes?
Post by: ghh on 13/03/2014 16:24:11
I have done an analysis of the nuclear properties of Isotopes, which you may find interesting

The files are too large for attachments so I have put them in Google docs
The main paper is Isotope Analysis.pdf
https://drive.google.com/file/d/0B3pdkE0Liyu2eHBGMk9zMzhjRWc/edit?usp=sharing

The supporting data sheets are all Excel spreadsheets:

Isodata.xls is the main data capture document
https://drive.google.com/file/d/0B3pdkE0Liyu2YTZ2bVFORFVzYTQ/edit?usp=sharing

IsosortA.xls is the same data sorted by nuclide number, and then by Proton number. This contains the initial sorting codes and colour highlights
https://drive.google.com/file/d/0B3pdkE0Liyu2QXdad3FReFZlaFk/edit?usp=sharing

Stabanal.xls is the analysis of the stable isoropes (including the 2beta stable)
https://drive.google.com/file/d/0B3pdkE0Liyu2eldSby04clRvTlU/edit?usp=sharing

IsosortB.xls expands the sorting codes, and contails the mass calculations
https://drive.google.com/file/d/0B3pdkE0Liyu2UGFaZ3VMSEhFcWM/edit?usp=sharing

OPanal.xls analyses the “orphan Parents”
https://drive.google.com/file/d/0B3pdkE0Liyu2ZzloUlZPdkJITEE/edit?usp=sharing


DEanal.xls analyses decay energy patterns
https://drive.google.com/file/d/0B3pdkE0Liyu2OWZiUDBqeEhGbGs/edit?usp=sharing

headanal.xls looks at the isotoes which ar the “heads” of the nuclide number set
https://drive.google.com/file/d/0B3pdkE0Liyu2RDVsY2t2YWFzSEk/edit?usp=sharing

ANMandDensity.xls has the main curves for these values

Helium3and4.xls

I would have thought this would have some comments by now?

Some observations on abundance:
The data for this is in spreadsheet Fe56-58.xls which can be downloaded from
https://drive.google.com/file/d/0B3pdkE0Liyu2SFJlYVpWclFueVk/edit?usp=sharing


From this the nuclear density curves can be drawn for the decay chains leading to the stable Isotopes.
 As can be seen the diagram for 56Fe is considerably more complex than those for 57 and 58. This complexity is mainly due to the multiple decay modes of some Isotopes.
The data tables therefore also show the relative probabilities of the daughter Isotopes.
It is clear from the data that the most probable decay mode also has the highest decay energy. This allows a reasonable estimate of the proportions even where a probability is not given in the source data.

From the raw data, 56Fe has seven source isotopes; 57Fe has six source isotopes; and 58Fe has just four. But this simple view can be misleading.

In 56 Fe the chain from 61AS has only a 0.023% probability in the decay from 60Ge to 56Ni. Similarly the decay from 57Ti is only 0.3% and from 57V only 0.4%.

In the 57 chains only 58Sc has a full yield to 57Fe. The decay of 59Sc gives only 30% leading to 57Fe; similarly 58Ga allows 35% from 57Zn; 60As 35% also from 57Zn; and 59Ga only 3% at 58Zn.
The remaining chain 57Ca is shared with 56Fe which takes 30% of the initial decay and another 33% at 57Sc.
The net yield to 57Fe is 66% of 70% or only 46.2%

For 58Fe the chain from 59Sc is 70% in favour, but at 59V less than 1% continues to become 58Fe.
The chain from 59Ga (and 59Zn) effectively terminates at the extremely long lived 2 beta decay 58Ni. Leaving just the chain from 58Sc, and the OP2 58Co.

Why? Just because you find something interesting it doesn't mean that others will. In any case the reader needs to know how to access those files and you didn't post how to do that. Not that I'm interested.

You just download them
You get a preview so you can check there is nothing dodgy

I tried that and got this message

Sorry set the permissions incorrectly.

You should now be able to get it

I suppose it hasn't helped that all the acess permissions were set incorrectly!

Could someone please check that the files can now be read?

thanks. G

I tried two files, downloaded. So it works.

jccc, I've moved your posts including "enertron" theory to the New Theories forum.  You've been asked several times to stop posting your own theories here.  We may restrict your posting rights if you continue to do so.
