I've just completed an experiment using a laser to excite electons and hole in a germanium sample, and i want to fit a curve to some of the dat i've collected n origin, but i need to set up some initial parameters and i don't know how to work out what the origional number of injected holes.(adsbygoogle = window.adsbygoogle || []).push({});

So does anyone know, round about, the number of injected holes from a pulsed laser light?

Or how to do my fit in origin

f(x) = h*(exp(-a*x))*(1/((b*(x+(1/a)))^0.5))*(exp((-(c-(d*x))^2)/(b*(x+(1/a)))))

thanks
