Surface of Ni plate at 1000C contains 50% Ni (radioactive) and 50% Ni (non-radioactive). 4 microns below surface Ni63/Ni = 48:52 Lattice constant of Ni at 1000 C is 0.360 nm. Experiment shows that self-diffusion of Ni is 1.6 x 100 cm/sec . What is the flux of Nie atoms through a plane 2 um below surface?
