We have efficiently loaded a vapor cell magneto-optical trap from an orthotropic source of {sup 221}Fr with a trapping efficiency of 56(10){percent}. A novel detection scheme allowed us to measure 900 trapped atoms with a signal to noise ratio of {approximately}60 in 1sec. We have measured the energies and the hyperfine constants of the 7 {sup 2}P{sub 1/2} and 7 {sup 2}P{sub 3/2} states. {copyright} {ital 1997} {ital The American Physical Society}
