After the publication of the short note with the above title we have learnt that the level scheme proposed for the nucleus 70Br is identical with the low-energy part of the level scheme of 193Tl [1] as presented in [2].

This nucleus could be populated in our experiment via the reaction 181Ta(16O,4n) in the beamstop made of tantalum.

The assignment of the $\gamma$ rays at 392, 406, 735, 751 and 754 keV to the nucleus 70Br was based on the analysis of ratios of $\gamma-\gamma$ intensities from exit channels with different neutron and proton multiplicities, which are presented in Figs. 2-4 of the short note. This analysis gave a consistent picture. The

critical point was that the assignments to 3n as well as 1p were extrapolations, since there were no known exit channels with 3n or 1pemission that could be used for comparison.

In conclusion, the level scheme presented in the short note displays excited states in 193Tl. The identification of excited states in 70Br remains an open problem.
