ELECTROMAGNETIC PROPERTIES OF NUCLEON RESONANCE N'(1470)

By applying the sidewise dispersion relation to the electromagnetic, π-N, and gravitational vertex functions of the nucleon and N′ (1470) while dominating the intermediate states by one-particle states, we show that the magnetic form factor of N′ (1470) and the magnetic transition form factor between N′ (1470) and the nucleon are proportional to the magnetic form factor of the nucleon with known proportionality constants. We also show that the electromagnetic mass difference of N′ (1470) is proportional to the p-n mass difference with the same proportionality constant. © 1969 The American Physical Society.
