Measuring the spintransfer coefficient for n,Used
Delivery time: 8-12 business days (International)
Scientists use carefully designed experiments to acquire basic understanding of the physical world. A large number of physics experiments are done by scattering various particles to study their behavior thus to gain insight into how they interact. In studying the nuclear force, neutronproton scattering provides an unique angle into learning how fundamental particles such as nucleons interact with each other. One basic parameter in describing the NucleonNucleon (NN) interaction is the pNN coupling constant, the precise value of which has been in great controversy. Different models of physics give values differing up to 10%. The accuracy of the pNN coupling constant is important in understanding nucleonnucleon interactions as well as other related phenomena such as chiral symmetry breaking in field theories and properties of twonucleon systems such as the deuteron. In neutronproton (np) scattering, the spintransfer coefficient KNN' is a measurable quantity which directly relates to the p+/ NN coupling constant, g2c. Precise measurement of the spintransfer coefficient can be used to put constraint on the coupling constant, thus improve the accuracy of its value.
