We picked some TEM photos in which crystal particles were relatively evenly distributed, did random analysises by using software, to first identify the center of a crystal, then did same for the  neighboring particles. We then measure the distance from the center of one crystal to the same of the others,  and then repeated the same measurement, only to change it from center-to-center to from the surface of a crystal to the same of the others, and plotted the data into a histogram.

Among all isotopes of the element Zinc, only 67Zn possesses self-spin property. Due to the facts that it is low in the natural abundance (only 4%), and it has a very strong quadruple effect, together with a low frequency in resonance, we were unable to obtain any  measurable signals.
