  In this report, femtoscopic measurements with proton-proton,
antiproton-antiproton, proton-antiproton, proton-antilambda, antiproton-lambda
and lambda-antilambda pairs in Pb-Pb collisions at sqrt(s_NN)=2.76 TeV
registered by ALICE at the LHC are presented. Emission source sizes extracted
from the correlation analysis with (anti)protons grow with the event
multiplicity, as expected. A method to extract the interaction potentials (e.g.
for proton-antilambda and antiproton-lambda pairs) based on femtoscopy analysis
is discussed. The importance of taking into account the so-called residual
correlations induced by pairs contaminated by secondary particles is emphasized
for all analyses mentioned above.
