摘要：

The effect of the neutron to proton ratio of the colliding system on the isotope ratio of the emitted fragments (1 less than or equal to Z less than or equal to 5) was studied for for a variety of constant mass beam-target combinations. To extend the N/Z ratio as far as possible, one of the projectiles employed, Cl-40, was a radioactive secondary beam. The isotopic ratios depend on the N/Z of the target and beam in a way which is not consistent with N/Z equilibration on the timescale of the emission of intermediate-mass fragments.
