We have observed macroscopic quantum transitions in a symmetric double well potential (a SQUID with 'fl o /2 of external flux). The transition rate r ll( exp[-BliU/hwol has been measured vs. li U, the barrier height, for fixed temperature. This is achieved by modulating the barrier height in situ wi
