kinematic factor @ 2.000 ±0.001 MeV

    Si: 1749.21 ± 0.01



can find a ratio between the lithium and flourine cross-sections

    taking the ratio of the yields and cross-sections allows things like target thickness to drop out

what you're after: the yield and the cross-section are basically proportional to each other

in lab write-up



A big danger:

    Flourine curve very sensitive to different in energy of about .1, so this could change your ratio greatly
    this would be a systematic error that caused an energy shift to explain wrong values
