We demonstrate both theoretically and experimentally that the two-pulse sequence (2n + 1) ·90Yo-90Xo-Acq(t) without delay between the pulses yields the reverse of the time evolution of spin systems with quadrupole interactions. This process results in refocusing of the spin magnetization into a magic echo at te = t1/2 after the second pulse, where t1 is the length of the first pulse. 33.25.+k; 76.20.+q; 76.60.-k; 76.60.Lz.
