Abstract

We have efficiently loaded a vapor cell magneto-optical trap from an orthotropic source of

^{221} Fr

with a trapping efficiency of 56(10)%. A novel detection scheme allowed us to measure 900 trapped atoms with a signal to noise ratio of

\sim 60

in 1 sec. We have measured the energies and the hyperfine constants of the

{}^{2}{7 P}_{1 / 2}

and

{}^{2}{7 P}_{3 / 2}

states.
