Abstract
We have remeasured the decay of Ar-31 with a setup sensitive to multipartic le decay branches and obtained. a new limit of 1.1 x 10(-3) (99% C.L.) on t he beta-delayed three-proton branch between the isobaric analog state in Cl -31 and the ground state of Si-28. This a factor of 17 below the previously reported first observation of beta-delayed three-proton emission in Ar-31. The limit on a possible beta 3p branch to the first excited state in Si-28 is 2.9 x 10(-4). [S0556-2813(99)04404-0].
