520 ⊔ ⊔ ‡aThe series of beta-active nuclei with (4n+2) primary particles, He(6), Be(10), C(14), F(18), Na(22), etc. has created much discussion because some of its members show allowed transitions while others are forbidden. It seemed possible that the allowed cases might represent transitions to excited states; if so, a consistent rule would govern the transitions to the ground states. However, the results given herein seem to exclude this explanation, unless the unlikely assumption of a very low energy gamma ray is made.
