Abstract
The classical four-pulse experiment of Waugh, Huber, and Häberlen (WAHUHA) is extended to the upper limit in pulse width which is possible in the four-pulse timing, i.e., the pulse width equals 1/6 of the cycle time. It is shown that coherent averaging is still in effect and high resolution in solids can be achieved to the same extent as in the δ pulse limit.
