The analysis of a large body of heavy ion fusion reaction data with medium-heavy projectiles (6$$leq$$Z$$leq$$18) and actinide targets suggests a disappearance of the 3$$n$$ exit channel with increasing atomic number of the projectile. Here, we report a measurement of the excitation function of the reaction $$^{248}$$Cm($$^{26}$$Mg,$$xn$$)$$^{274-x}$$Hs and the observation of the new nuclide $$^{271}$$Hs produced in the 3$$n$$ evaporation channel at a beam energy well below the Bass fusion barrier with a cross section comparable to the maxima of the 4$$n$$ and 5$$n$$ channels. This indicates the possible discovery of new neutron-rich transactinide nuclei using relatively light heavy ion beams of the most neutron-rich stable isotopes and actinide targets.
