Measurement of the γ emission probability of 173Yb using surrogate reactions

We performed the 174 Yb(p,d) reaction in order to measure the gamma-emission probability of 173 Yb. The identification of the ejectiles — allowing us to tag the production of 173 Yb nuclei — was performed using the STARLiTeR detector system. Unusually, the "statistical" γ-rays were used to determined the gamma- emission probability and a spin distribution was extracted from it. A comparison with the spin distribution from the 174 Yb( 3 He,α) reaction shows that the transferred angular momentum is similar in both reactions.
