      abstract = {We discuss the consequences of the quantum uncertainty on  the spectrum of the electron emitted by the 𝛽-processes of  a tritium atom bound to a graphene sheet. We analyze  quantitatively the issue recently raised by Cheipesh,  Cheianov, and Boyarsky [Phys. Rev. D 104, 116004 (2021)],  and discuss the relevant timescales and the degrees of  freedom that can contribute to the intrinsic spread in the  electron energy. We perform careful calculations of the  potential between tritium and graphene with different  coverages and geometries. With this at hand, we propose  possible avenues to mitigate the effect of the quantum  uncertainty.},
