Double lift Double lift A double lift is a sleight of hand maneuver used by magicians in card magic. It is a method by which the identity of the top card may be kept secret by lifting the top two cards as one, making it seem as if only the top card is picked up. Similar techniques may be applied to more than two cards to perform a triple or even quadruple lift. The term was coined by Theo Annemann. When the card is shown to the audience, the audience is tricked into believing that they are shown the top card in
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,
