Abstract: Predicting magic wavelengths accurately requires precise knowledge of electric-dipole matrix elements of nearby atomic transitions. As a result, measurements of magic wavelengths allow us to test theoretical predictions for the matrix elements that frequently can not be probed by any other methods. Here, we calculate and measure a magic wavelength near $473$ nm of the $5s^2\,^1\!S_0 - 5s5p\,^3\!P_1$ intercombination transition of ${}^{88}$Sr. Experimentally, we find $473.361(4)$ nm for $\Delta m=0$ ($\pi$ transition) and $473.133(14)$ nm for $\Delta m=-1$ ($\sigma^{-}$ transition). Theoretical calculations yield $473.375(22)$~nm and $473.145(20)$ nm, respectively. The $^3\!P_1$ polarizability is dominated by the contributions to the $5p^2\, ^3\!P$ levels and excellent agreement of theory and experiment validates both theoretical values of these matrix elements and estimates of their uncertainties.

We observe a significant increase in the steady state number of atoms in the magneto-optic trap (MOT) This enhancement is attributed to the efficient repumping of atoms that have decayed into the dark $5s5p;3P$ state. Our calculated hyperfine-splitting energies are in excellent agreement with the measured values.
