The 6.2 keV level of /sup 181/Ta(T/sup 1///sub 2/ = 6.8 ..mu..s) belongs to the few Moessbauer resonances with lifetimes in the microsecond region. The corresponding natural linewidth, W/sub 0/ = 6.5 ..mu..m/s, has not been observed so far. In spite of many efforts, the best experimental linewidths are still a factor of approximately 10 larger than W/sub 0/. A new method of source preparation from cyclotron-produced, carrier-free /sup 181/W activity, which yields either an improvement in the experimental linewidth or in the source efficiency.
