..cap alpha.. decay for thallium isotopes has never been clearly established. In this study thallium and mercury nuclides were produced by (/sup 14/N, xn and pxn) reactions induced by 168-MeV /sup 14/N bombardments of /sup 182/W and investigated using an on-line mass-separator facility. ..cap alpha..-particle and ..gamma..- and x-ray spectral measurements were made simultaneously. At A=186 a new ..cap alpha.. peak was observed with E/sub alpha/=5.641 +- 0.010 MeV; we assign it to 28-sec /sup 186/Tl. By assuming the 405.3-keV (2/sup +/..-->..0/sup +/) transition to encompass the EC/..beta../sup +/ decay of 28-sec /sup 186/Tl its ..cap alpha..-decay branch was determined to be (6 +- 2) x 10/sup -4/. Measurements at A=184 and A=185 revealed no ..cap alpha.. groups that could be assigned with any certainty to /sup 184/,/sup 185/Tl. The measurements did, however, corroborate the ..cap alpha..-decay energies and total half-lives for /sup 183 -185/Hg as reported by P. G. Hansen et al. (AIP)
