    "abstract": "A test on quantum mechanics proposed long ago by Karl Popper is reconsidered\nwith further detail and new insight. An ambiguity in the proposal, which turns\nout to be essential in order to make the test conclusive, is identified and\ntaken into account for the first time. Its implications for recently performed\nphoton experiments [such as in D. V. Strekalov \\textit{et al.}, Phys. Rev.\\\nLett. {\\bf 74}, 3600 (1995)] are briefly analyzed.",
