BErkeley Alpha and proton Radiation (BEApR) database: an On-line Heavy Charged-Particle Decay Database

The Berkeley data group have launched an online database BErkeley Alpha and proton Radiation (BEApR) detailing all known information on beta-delayed and direct heavy particle emitters (p, $alpha$, fission). This includes branching ratios, T$_{1/2}$, and all relevant Q and particle separation values. These are listed for all nuclei where these decays are energetically possible. In addition, for nuclei with known discrete proton and alpha transitions, the particle energies, intensities, initial and final states are compiled. A figure showing the major decays and a list of experimental references is also given for each dataset. Nuclei are organized by their isospin projection (Tz) and alpha-chain in this database, and split into even and odd Z. Information for this database is primarily obtained through a combination of NSR, google scholar, and IAEA.

At the time that this abstract was submitted, complete evaluations/compilations from Tz=-4 to Tz=+13 are included. Tz groups will be added at a rate of $approx$1/week up to the very heaviest nuclei known (Tz=+30), and will be updated as new papers are published. The tables in this database can be currently downloaded as a pdf document, and we will soon be offering them in a JavaScript Object Notation (JSON) format.

This database is now live and can be accessed at:
