Undergrad List of hyperfine structure of the elements?

Click For Summary
The discussion revolves around the hyperfine structure frequencies of various elements, specifically mentioning caesium and hydrogen. A participant seeks a comprehensive list of these frequencies for other elements and isotopes, expressing curiosity about potential patterns in the data. They reference a 2016 paper detailing numerous newly discovered lines for lanthanum, highlighting the complexity and volume of such information. There is skepticism about the ability to identify patterns manually, but the search for existing resources continues. The conversation emphasizes the need for accessible databases or papers on hyperfine structures.

If caesium 133 frequency for its hyperfine structure is 9 192 631 770, and hydrogen is 1 420 405 751.7667 what are the frequencies for the other elements and their isotopes? Is there a list on line some were because this would be a long list. Any help on where to look on line would be appreciated. Thanks.

I have found a paper with a list of "Newly Discovered Lines of Lanthanum Between ##5600 \,Å ## and ##6100\,Å ##" published in 2016. Their list alone contains several hundred entries. This raises the question: Why?

I want to see if there is any patterns in the frequencies. Maybe you could predict the frequency of an isotope or maybe other information. I know other people must of looked at this but I am still curious. How can I find this paper? Thanks.
 
The paper wasn't in English. I don't think there is a chance to identify patterns, at least not manually, but I don't know. I just found it (quickly) as I searched for "hyperfine structure + list" and was surprised to find so many for just one element and even labelled "new".
 
The patterns for hyperfine structure as as "patterned" as those for any other energy level.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
