In Ed's scenario, this may be possible. Namely, if sufficient mass is lost before the reaction occurs, such that there is insufficient remaining to form a positron. However this implies that whatever the mechanism that disperses the energy prior to the reaction, it must always get rid of a minimal amount each time, in order to ensure that no positrons are formed.

UV or soft x-rays are >ok but no gammas The obvious conclusion here would be that no nuclear reaction takes place. Just f/H formation. Note: I have previously proposed nuclear reactions where the energy is carried by a heavy charged particle, and stated that these were gamma-less. That's not quite true, as occasionally a heavy particle will collide with a nucleus and excite it, such that it emits a gamma when it decays back to the ground state. These secondary gammas should be detectable, and the fact that they are missing virtually rules out fast particles as the means by which energy is dispersed.
