    "abstract": "In this paper we extend the ladder proof of nonlocality without inequalities\nfor two spin-half particles given by Boschi et al [PRL 79, 2755 (1997)] to the\ncase in which the measurement settings of the apparatus measuring one of the\nparticles are different from the measurement settings of the apparatus\nmeasuring the other particle. It is shown that, in any case, the proportion of\nparticle pairs for which the contradiction with local realism goes through is\nmaximized when the measurement settings are the same for each apparatus. Also\nwe write down a Bell inequality for the experiment in question which is\nviolated by quantum mechanics by an amount which is twice as much as the amount\nby which quantum mechanics violates the Bell inequality considered in the above\npaper by Boschi et al.",
