Abstract
The Baldin sum rule for the nucleon has been recalculated at the light of the most recent photoabsorption cross section measurements. The pr oton value (alpha + beta)(p) = 13.69 +/- 0.14 is smaller but consisten t with the one usually quoted in literature. However, the value for th e neutron (alpha + beta)(n) = 14.40 +/- 0.66 turns out to be three sta ndard deviations away from the previously calculated one.
