One experiment that attempted to resolve this problem, proposed by Lederman and Garwin, and performed using a cyclotron known as the "pie factory," involved placing a six by one inch block of carbon wrapped in a wire coil in the path of streaming mu mesons. The genesis of this problem involved the observations of unusual decay patterns of cosmic rays by C.F. Powell, and R.H. Dalitz proposed that the particles in question could not be the same. Violating Laporte's selection rule, a proposed solution was offered in the paper, "Question of Parity Conservation in Weak Interactions," written by Lee and Yang, and was experimentally confirmed by Wu using super-cooled Cobalt 60 atoms. For 10 points,
