Bata-gamma angular correlations and beta spectra of the first forbidden beta transitions of ^<122>Sb have been studied. The result of the angular correlation measurement of the (734keV β, 1256keV γ) cascade indecates deviation from the ξ approximation for the 734keV β transition. The analysis using exact electron radial functions which include finite nuclear size corrections shows that cancellation exsis among the matrix elements. Thus. the ξ approximation is not fulfilled. The nuclear matrix parameters fitted to the angular correlation data are x=0.34±0.44, u=2.03±0.96, y'=25.0±13.8, w=1.63±4.94 and v'=-18.4±53.5. These parameters describe well the measured spectrum of the 734keV β transition which shows deviation from the allowed shape. A comparison between the experimental results and the theoretical prediction based on the CVC theory is given.
