We derive a Bell inequality which is easier to test and requires slightly weaker supplementary assumptions than the popular no-enhancement assumptions. It can be shown that this new Bell inequality is violated by quantum mechanics with a factor of 1.92 (C) 2000 Elsevier Science B.V, All rights reserved.
