Global properties of nuclear decay modes

Koura, Hiroyuki   ; Tachibana, Takahiro*; Chiba, Satoshi

We have developed an original model based on the macroscopic and mean-field models to describe the global features of nuclear masses, called the KTUY (Koura-Tachibana-Uno-Yamada) nuclear mass model. The standard deviation of this prediction from known masses is 0.67 MeV, and below 0.4 MeV from some separation energies. The calculated separation energies shows a change of magicities from =20 (or 14) to 16, =28 to 32 (or 34), =50 to 58 etc.-decay, -decay, proton emission and spontaneous fission ranging from light nuclei to superheavy nuclei including unknown ones, and estimated the dominant nuclear decay modes. A file of these nuclear data is presented. The total number of nuclei having more than 1 ns is estimated to be approximately ten thousands.
