Resumen: We have remeasured the decay of Ar-31 with a setup sensitive to multiparticle decay branches and obtained a new limit of 1.1 x 10(-3) (99% C.L.) on the β-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 β-delayed three-proton emission in Ar-31. The limit on a possible β3p branch to the first excited state in Si-28 is 2.9 x 10(-4).
