Abstract
It is shown that data on the dissociation rate of deuterium obtained in an experiment at the Sudbury Neutrino Observatory provides evidence that the Continuous Spontaneous Localization wavefunction collapse model should have mass–proportional coupling to be viable.

A 42, 1057 (1990) is essentially equivalent to CSL with mass-proportional coupling (the property tested in this paper). The gravitationally based collapse criterion of R. Penrose, Gen. Rel. and Grav. 28, 581 (1996) is not a dynamical theory. The energy-based collapse model of L. P. Hughston, Proc. Roy. Soc. Lond. A, 452, 953 (1996)has been elucidated in S. L. Adler and L. P.

We note, until the uncertainty is reduced by that amount, the results are also consistent with baryon number proportionality. This would imply, e. g., that a macroscopically distinguishable superposition of leptons or of mesons would never collapse, and one might regard that as an undesirable feature of a collapse model.
