Angular Correlation with 134 Pr
نویسنده
چکیده
The decay of Pr produced in a nuclear fusion evaporation reaction was observed using the GAMMASPHERE array of over 100 Compton suppressed high-purity germanium γ-ray detectors. Selected γ-rays from bands 1, 5, and 6 were studied through a method of angular correlation to determine their multipolarities. The parity of band 6 could then be determined through analysis of these γ-rays’ multipolarities. Physics behind γ-ray Angular Correlation from Oriented States In nuclear fusion evaporation reactions, a beam nucleus collides with a target nucleus. The two fuse together and begin to spin before decaying. For this particular experiment the beam was Na and the target was Cd. Since a nucleus is measured in femtometers (10 meters), the distance between the two nuclei must be on a comparable scale for a collision to occur and for the nuclei to fuse. Central collisions are less probable then peripheral collisions, therefore, when two nuclei come in contact with one another the new nucleus will have an angular momentum given by the formula:
