I have analyzed the supernova SN 1181. It was first observed between August 4 and August 6, 1181, by Chinese and Japanese astronomers.
This is its energy spectrum from JS9 with its most importants energy peaks.
Then, I have calculated each peak's percentatge and find out which elements they contain.
I have used this formula:

Here are my results:

This supernova has:
- 68,5% of Cobalt (Co) which energy is 1377.5769 eV.
COMPARISON
I have compared my results with other scientific results. According to the scientific article element distributions in the crab nebula by Timothy J. Satterfield et al (2012) the supernova SN 1181 contains helium, carbon, nitrogen, oxygen, and sulfur.
- The chemical elements that I have obtain doesn't match to the results other astronomers got.
- Based on my investigation, this galaxy also contain cobalt but any article have talked about it.
- What I have done is to find the eV of the tallest peaks of the JS9 energy spectrum and discover what element corresponds to that enery.

I have calculated the electronvolt of this elements with the transition predetermined in this web (from the cap 3 to the 2). The atoms to jump from this capes have to be in a room temperature. Depending to the temperature, the element can have different energy. What is the same, a eV number can be from different elements if they are moving arround differents capes.
It can be possible that the atoms are not moving from the capes I have work with and this might be the reason why my results does not match with the scientifics results.
Another possibilty is that the element mentioned in the scientific article have a smaller quantum energy that the ones I got so it can be possible that the part of the galaxy I have worked with has more energy that the part analysed by the scientifics.
