|For heavy nuclei (approximately Z>114) some nuclei are calculated to be quite deformed in their ground states. For some of these nuclei very long alpha half-lives are obtained. However, these deformed, heavy nuclei are expected to have fission barriers only a few MeV high. Therefore the fission half-lives are expected to be very short. The long alpha half-lives are therefore not indicative that these nuclei may exist or be observable. In this heavy region only some spherical or near spherical nuclei can be expected to have half-lives that are sufficiently long to allow observation in experiments.|

If the calculated Tα is larger than 1020, it is not calculated, and in that case, we list in the last two columns the values
