We have determined the absolute intensity of weak γ transitions in the level scheme of ${}_{}{}^{144}{}_{}{}^{}\mathrm{Nd}$, observed following the electron capture decay of ${}_{}{}^{144}{}_{}{}^{}\mathrm{Pm}$. The absolute intensity of the 1397-keV E3 branch from the 2093-keV ($5_1^{\mathrm{-}}$) level was determined to be (4.9 ± 0.7) × ${10}^{\mathrm{-}4}$%. This leads to a revised absolute transition rate of B(E3;$5_1^{\mathrm{-}}$→$2_1^{+}$)=${26}_{\mathrm{-}12}^{+15\mathrm{}}$ Weisskopf units, which is still consistent with an interpretation of the $5_1^{\mathrm{-}}$ level based on quadrupole-octupole coupling. © 1996 The American Physical Society.
