GAMMA-GAMMA DIRECTIONAL CORRELATIONS IN Rh$sup 10$$sup 5$

Journal Article · · Nuclear Physics (Netherlands) Divided into Nucl. Phys. A and Nucl. Phys. B
Directional correlation measurements are made on the 320-475 kev and 485- -475 kev gamma-gamma cascades in Rh/sup 105/ following the decay of 4.5-hr half- life Ru/sup 105/ with a coincidence scintillation spectrometer using NaI detectors. The observed correlation functions are determined for the two cascades. These gamma-gamma directional correlations are found to be consistent with the spin assignment of 7/2, 7/2, 5/2, and 7/2 to the levels at the ground state, 475, 795, and 960 kev in Rh/sup 105/. The probable assignment of multipolarities for different gamma rays is as follows: the 475-kev gamma ray has a mixture of (30 to 55)% dipole and (45 to 70)% quadrupole; the 485-kev gamma ray has a mixture of (0 to 20)% dipole and (80 to 100)% quadrupole: and the 320-kev gamma ray has a mixture of (95 to 96,5)% dipole and (3.5 to 5)% quadrupole.
