The report stated that Wu, using cobalt-60 as a beta particle emission source and with the temperature controlled at an ultra-cold 0.003 Kelvin (approx. -273 ° C), corroborated the hypothesis of two other Chinese physicists, Yang Chen-ning and Lee Tsung-dao, proving that parity is not conserved in weak interaction, one of the four fundamental forces of the universe.
這篇報導說，吳健雄以「鈷 60」作為貝他粒子射線的放射源，在接近絕對溫度 0 度（0.003k，約攝氏零下 273 度）的極低溫控制下，首度證明另外兩位華人物理學家楊振寧與李政道的理論假設，證實「宇稱」在宇宙 4 個基本作用力之一的「弱交互作用」中不守恆。
