Need HELP! Muon Lifetime Experiment
I just recently collected data from a muon lifetime determination experiment. The data was presented in the form of two columns: x = time (microseconds) and y = counts/bin. After plotting this xy into a graph I found that my muon lifetime was 2.12 (close enough).
I was supposed to find a "combined fit" for the xy graph to:
N= Noe^(-t/tau) + C
Where tau is the mean lifetime. But! Haha! I simply took it upon myself to use excel trendline to determine the two separate components of fitting it. In the Excel attachment you will see what I mean by fitting the graph (by the two red dashed lines) One red line indicates the exponential component and the other red line indicates the constant (linear) background component.
What is key here is that I'm supposed to use a HISTOGRAM! Well, I am ashamed to say that I don't particularly know how to use a histogram as well as I wish. Besides that, I don't even understand conceptually what a histogram does with my data (which is also provided). How do I use a histogram to fit it to the above?
THANX
