A Cyclotron with a Proton Current of I = 2

question 26

Essay

A cyclotron with a proton current of I = 2 × 10¹⁴ protons/s is used to irradiate a target with n = 3 × 10²⁰ neutrons in order to produce N-13 (T_1/2 = 10 min). The cross-section for the reaction is ó = 3 × 10^-26 cm². Calculate the number of N-13 nuclei after 30 minutes of irradiation.
