N2 - We report measurements of the isotope shifts of the (3s3p)P30,1,2-(3s4s)S31 Mg I transitions for the stable isotopes M24g (I=0) , M25g (I=5/2) , and M26g (I=0) . Furthermore, the M25g S31 hyperfine coefficient A(S31)=(-321.6±1.5)MHz is extracted and found to be in excellent agreement with state-of-the-art theoretical predictions giving A(S31)=-325MHz and B(S31)¿10-5MHz . Compared to previous measurements, the data presented in this work are improved up to a factor of 10.
