Physics Researchers Question Calcium 52’s Magic

The image above shows the chain of the studied calcium isotopes. The “doubly magic” isotopes with mass numbers 40 (Ca-40) and 48 (Ca-48) exhibit equal charge radii. The first measurement of the charge radius in Ca-52 yielded an unexpectedly large result. For decades nuclear physicists have tried to learn more…
