Finite-energy sum rule for the nucleon polarizability difference
A finite-energy sum rule is derived for the difference between the electric (..cap alpha../sub N/) and magnetic (..beta../sub N/) polarizabilities of the nucleon. The new sum rule for the difference ..cap alpha../sub N/-..beta../sub N/ is used along with the sum rule found previously for the sum ..cap alpha../sub N/+..beta../sub N/ to calculate the polarizabilities of the proton and neutron. The calculated proton polarizabilities, ..cap alpha../sub p/= (9.0 +- 2) x 10/sup -43/ cm/sup 3/ and ..beta../sub p/= (5.2 +- 2) x 10/sup -43/ cm/sup 3/, agree well with the values ..cap alpha../sub p//sup expt/= (11.3 +- 2.5) x 10/sup -43/ cm/sup 3/ and ..beta../sub p//sup expt/= (2.9 +- 2.5) x 10/sup -43/ cm/sup 3/ found from a revised analysis of the experimental data.
