    "abstract": "We have successfully loaded a magneto-optic trap for Yb atoms from a thermal\nsource without the use of a Zeeman slower. The source is placed close to the\ntrapping region so that it provides a large flux of atoms that can be cooled\nand captured. The atoms are cooled on the ${^1S_0} \\leftrightarrow {^1P_1}$\ntransition at 398.8 nm. We have loaded all seven stable isotopes of Yb into the\ntrap. For the most abundant isotope ($^{174}$Yb), we load more than $10^7$\natoms into the trap within 1 s. For the rarest isotope ($^{168}$Yb) with a\nnatural abundance of only 0.13%, we still load about $4 \\times 10^5$ atoms into\nthe trap. We find that the trap population is maximized near a detuning of\n$-1.5\\Gamma$ and field gradient of 75 G/cm.",
