The beta-decay of the neutron-rich nucleus 110.sup.Mo, separated by the IGISOL on-line mass separator from other fission products, has been investigated by using beta-gamma and gamma-gamma coincidence techniques. The decay scheme of 110.sup.Mo has been revised, including 3 new excited states and 7 new [gamma] transitions in 110.sup.Tc. The [beta] -feedings were measured and ft values and B(GT) values were deduced based on a Q.sub.[beta] -value from systematics. Three excited 1.sup. + states in 110.sup.Tc fed by spin-flip allowed-unhindered beta transitions were identified. The deduced beta-decay strengths are compared with the Gamow-Teller strength distribution obtained from a macroscopic-microscopic calculation. The role of the asymptotic quantum numbers in the context of the allowed beta-decay is discussed.
