AbstractAbstract
[en] The 6.2 keV level of 181Ta(T1/2 = 6.8 μs) belongs to the few Moessbauer resonances with lifetimes in the microsecond region. The corresponding natural linewidth, W0 = 6.5 μm/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 W0. A new method of source preparation from cyclotron-produced, carrier-free 181W activity, which yields either an improvement in the experimental linewidth or in the source efficiency
