We present a measurement of the elastic differential cross section d\ensuremathσ(pp\ensuremath→pp)/dt as a function of the four-momentum-transfer squared t. The data sample corresponds to an integrated luminosity of \ensuremath≈31 nb^\ensuremath-1 collected with the D0 detector using dedicated Tevatron pp Collider operating conditions at √(s)=1.96 TeV and covers the range 0.26<|t|<1.2 GeV2. For |t|<0.6 GeV2, d\ensuremathσ/dt is described by an exponential function of the form Ae^\ensuremath-b|t| with a slope parameter b=16.86\ifmmode±\else\textpm\fi0.10(stat)\ifmmode±\else\textpm\fi0.20(syst) GeV^\ensuremath-2. A change in slope is observed at |t|\ensuremath≈0.6 GeV2, followed by a more gradual |t| dependence with increasing values of |t|.
