The study of the stability of an astrophysically interesting nucleus Rb-73 was performed by searching its beta(+) and proton decay at the ISOLDE facility at CERN. Light rubidium isotopes were produced in a spallation reaction of a niobium target induced by a pulsed 1 GeV proton beam, The previously reported proton-unbound character of Rb-73 was confirmed and the upper limit for its production cross-section was reduced by more than one order of magnitude.
