Hydrogen-5 is a highly unstable isotope of hydrogen. The nucleus consists of a proton and four neutrons. It has been synthesised in the laboratory by bombarding tritium with fast-moving tritium nuclei. [ [http://content.aip.org/APCPCS/v610/i1/920_1.html Cookies Required ] ] In this experiment, the one tritium nucleus captures two neutrons from the other, becoming a nucleus with one proton and four neutrons. The remaining proton may be detected, and the existence of hydrogen-5 deduced. It decays through neutron emission and has a half-life of 8.01930×10-23 seconds.
