Based on the values deduced from the linear extrapolations along isotopic chains and on the universal decay law, the proton- and -decay partial half-lives are calculated for odd-, even- neutron-deficient Bi-Pa isotopes. Eight proton-emission states in five new isotopes are suggested. The calculated half-lives for the 1/2 states in Bi and At are around 100 ns, too short to be studied using the recoil separator setups, which strongly encourages the development of new experimental techniques and devices to search for new submicrosecond proton-emitting nuclei.
