On the Equivalence of Experimental B(E2) Values Determined by Various Techniques

We establish the equivalence of the various techniques for measuring B(E2) values using a statistical analysis. Data used in this work come from the re- cent compilation by B. Pritychenko et al., At. Data Nucl. Data Tables 107 (2016). We consider only those nuclei for which the B(E2) values were measured by at least two different methods, with each method being independently performed at least twice. Our results indicate that most prevalent methods of measuring B(E2) values are equivalent, with some weak evidence that Doppler-shift attenuation method (DSAM) measurements may differ from Coulomb excitation (CE) and nuclear resonance fuorescence (NRF) measurements. However, such an evidence appears to arise from discrepant DSAM measurements of the lifetimes for 60Ni and some Sn nuclei rather than a systematic deviation in the method itself.
