I assumed that if i had the total number of neutrons of the CO-59 and added it to the number of neutrons that came from the flux, i could find the total number of Co-60 neutrons and then find how many nuclei from that.
Co-60 is produced from Co-50 through neutron activation. Neutron flux 10^18 nuetrons/(s*m^2). cross section is 20 barns and the mass of Co-50 40mg. How many Co-60 are produced in one week?
My attempt:
I multiplied the flux by the seconds in one week and by 20 barns in m^2 and got 0.0122...
When solving a differential equation for Bessel Functions, how do you know when to use the 1st kind or Neumann functions. How do you know which order of the bessel function to use?
