Based on the Q(p/alpha) values deduced from the linear extrapolations along isotopic chains and on the universal decay law, the proton- and alpha-decay partial half-lives are calculated for odd-Z, even-N neutron-deficient Bi-Pa isotopes. Eight proton-emission states in five new isotopes are suggested, including the 1/2(+) and 9/2(-) states in Bi-183, the 1/2(+) and 7/2(+) states in 187,189At, the 1/2(+) state in Fr-193, and the 9/2(-) state in Ac-199. The calculated half-lives for the 1/2(+) states in Bi-183 and At-187 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.
