Interpretation of isomeric transitions of electric quadrupole type
A Bohr, BR Mottelson - Physical Review, 1953 - APS

Selection rule for bosons
JB Bronzan, FE Low - Physical Review Letters, 1964 - APS
(A) In this Letter we point out that the evidence on boson decays is consistent with an
empirical selection rule, which me call A invariance.'A invariance is compatible with, but …
