The {sup 2} S{sub 1/2}-{sup 2}F{sub 7/2} electric octupole (E3) transition in {sup 172}Yb{sup +} has been detected by observing quantum jumps in a single laser cooled ion, stored in an electrodynamic trap. The transition frequency is 642116785.3(0.7)MHz (1{sigma}). Consideration of the transition rate and laser parameters implies a {sup 2} F{sub 7/2} level lifetime of 3700 days. This is the first time an atomic E3 transition has been driven. This transition has applications as an optical frequency reference. {copyright} {ital 1997} {ital The American Physical Society}
