Looking up Atomic Transition Energies

  1. Jun 5, 2012 #1

    I am looking at strontium, and I wish to find the difference in energy between the 1S0-1P1 transition (~ 461nm) in Sr-88 and Sr-86. I don't need to calculate it, I need to look it up in a table. I thought that NIST would be helpful (http://physics.nist.gov/PhysRefData/ASD/lines_form.html), but I didn't get anything useful from there. Most likely it is because I don't know how to use it properly.

    When I type in Sr, I get all the ions (Sr I, Sr II, ...). How do I know which one Sr-88 and Sr-86 is?

    Best wishes,

    I don't think that site has the data you need. However, when you click on the
    bibliography links they supply above the table, you are led to this article:

    http://jpcrd.aip.org/resource/1/jpcrbu/v39/i3/p033103_s1 [Broken]

    which is fairly recent (2010) but does not give a value for Sr86 1p1 --> 1s0, only 3p1 --> 1s0.

    I'm afraid you are out of luck.

    Thanks. Seems like I am out of much luck these days.. but that's life I guess. I found a thesis (http://www.owlnet.rice.edu/~killian/publications/MickelsonThesis.pdf, PDF page 20, thesis page 10), where there is a figure. But I don't know how the author got these values.

    Write him or his supervisor? Worst that can happes is the don't answer. Best is they offer you a job :-) (happened to me, no joke)

    I tried writing him, lets see what happens. He must be very desperate if he offers me a job.

    lol, it did not happen after the first e-mail... But good luck, anyways

    BTW, my job offer was for doing a PhD, nothing more.

    If one looks for 'atomic' (electron) transition data, then unless specified, one would like get results from a sample with all naturally occuring isotopes.

    Sr-84(0.0056), Sr-86 (0.0986), Sr-87 (0.070) and Sr-88 (0.8258)

    Perhaps this might lead to something
