Some studies in nuclear structure by coincidence measurements
Stockholm University, Faculty of Science.
1983 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

The coincidence technique is a basic method for determining nuclear parameters. From single and coincidence gamma-ray measurements, using high resolution Ge(Li) detectors, a level scheme of ^ ^Sb was determined. Directional correlations of gamma-gamma electromagnetic radiations from cascades in ^Zr, and ^^Bi have been measured, using a twelve-channel goniometer. Multipole mixing ratios of the involved gamma transitions were determined. The use of two Ge(Li) X-ray and two Ge(Li) gamma-ray detectors for coincidence measurements in ^°®Dy, made it possible to determined anisotropic directional correlations between gamma-rays and L X-rays following internal conversion for the first time. The half-life of the first excited 9/2+ state in ^Ag has been measured by the delayed-coincidence technique. The energy level structure of ^Ru was studied by using the reactions ^^Mo^He^n) and ^®Mo(^He,2n). From the measured excitation functions, gamma-gamma coincidences, and gamma-ray angular distributions, a level scheme with three collective bands was constructed. Some of the above experimental results have been compared with current nuclear models.
