Abstract
- Gamma-ray angular distributions in oriented 92 Mo produced via the 6 Li+ 89 Y reaction were studied in this work. The characteristic γ rays in 92 Mo were measured by means of the GALILEO array, which is composed of 25 Compton-suppressed HPGe detectors arranged in a nearly 2 π geometry. A detailed analysis of the spin-alignment attenuation factors ( α 2 ) for different excited states in 92 Mo was performed, by analyzing the measured angular distribution coefficients of several pure-E2 transitions. The relationship between α 2 and the spin was established in 92 Mo and the 244-keV transition between the 5 1 - and 4 1 + states resulted to have a E1 + M2 character with a mixing ratio (δ ) of - 0. 05 - 0.06 + 0.05 , consistent with shell model calculations.
