The differential cross sections for the ${\mathrm{C}}^{13}({\mathrm{He}}^3, \alpha ){\mathrm{C}}^{12}$ reaction have been measured for ground state and first excited state $\alpha$-particle groups at a bombarding energy of 2.00 Mev for sixteen center-of-mass angles extending from 5 to 152 degrees. These data have been fitted with Legendre polynomial expansions including polynomials up to the sixth degree by the method of least-squares. The coefficients in these expansions and the total cross sections are tabulated.
