Ununoctium (Congratulations you have an unlimited source of an element that only 4 atoms of it were made, EXTREMELY RADIOACTIVE, decays extremely quickly) EDIT FROM LOLZY: If this was facebook, i would like this.
what about He2+ particles (alpha particles) I think some one made a beta with them, but i never used/saw it. Pu could give of He2+ particles occasionally (when its not critical) and give off neutrons when it is in an nuclear reaction. Pu particles that undergo alpha decay should turn into U (I think the half life should be shortened though )
