Quadruple jump controversy important. It's good for me to keep challenging myself. I can't hold back on anything, and taking chances is what sports are about." Plushenko's program was more ambitious and risky with the quadruple toe/ triple toe loop, while Lysacek did not even attempt the quad as a single jump "at the biggest moment on skating's biggest stage." Sports journalist Kevin Blackistone wrote: "What has unfolded at the Vancouver Winter Games in figure skating would be the equivalent of not crediting Shaun White for his double McTwist in the half pipe and rewarding less ambitious snowboarders for getting the basics perfect."
Double beta decay or double beta decay are predicted to be very long; hence, quadruple beta decay is unlikely to be realized. The eight candidate nuclei for quadruple beta decay include Zr, Xe, and Nd capable of quadruple beta-minus decay, and Xe, Ba, Gd, and Dy capable of quadruple beta-plus decay or electron capture. In theory, quadruple beta decay may be experimentally observable in three of these nuclei, with the most promising candidate being Nd. Double beta decay In nuclear physics, double beta decay is a type of radioactive decay in which two neutrons are simultaneously transformed into two protons, or vice versa,
