Abstract
The decay of W-170 formed in reactions with two different projectile - target combinations was studied. The observed differences in the ave rage number of emitted neutrons suggest an entrance channel effect at the highest excitation energy and angular momentum. It may be explaine d by different excitation energies of the equilibrated system, resulti ng from the emission of pre-equilibrium alpha-particles during a longe r fusion time, in the more symmetric reaction.
