These so-called "invisible"decays do not directly deposit energy within the detector but are instead detected through their subsequent nuclear deexcitation and gamma-ray emission. New limits are given for the partial lifetimes: t(n?inv)>9.0×1029 years, t(p?inv)>9.6×1029 years, t(nn?inv)>1.5×1028 years, t(np?inv)>6.0×1028 years, and t(pp?inv)>1.1×1029 years at 90% Bayesian credibility level (with a prior uniform in rate). All but the (nn?inv) results improve on existing limits by a factor of about 3.
