Abstract: An exotic cluster model of 238 U is extended to allow nonzero E1 transitions to proceed between states of the negative and positive parity bands and the formalism required for the calculation of B(E1) and B(E2) values within the model is presented. Comparison of theoretical values with experimental data is made for the ratios B(E1; J i → J i + 1)/B(E1; J i → J i − 1) and B(E1; J i → J i − 1)/B(E2; J i → J i − 2)—in both cases from negative parity initial states. Good agreement is obtained with the data of Ward et al (1996 Nucl. Phys. A 600 88) and it is concluded that any rotational model should provide an adequate account of their data.
