The sta.da.d model of sonoluminescence suggests tha. the Coulomb ba.rier to deuterium fusion ma. be ov.rcome by high bubble ga. tempera.ures ca.sed by compression hea.ing if the bubble dia.eter rema.ns spherica. during bubble ***, in the more likely colla.se geometry of a.pa.ca.e sha.e, the tempera.ure rise in the bubbles is negligible. But the colla.sing pa.ca.e bubble is found to significa.tly increa.e the frequency of the infra.ed energy a.0}ila.le in the v.bra.iona. sta.e of the wa.er molecules a. a.bient tempera.ure. For a.colla.se to liquid density, ultra.0}olet ra.ia.ion a. a.out 10ev.is found. a.though the ultra.0}olet ra.ia.ion is of a.low intensity, higher intensities ma. be possible if the bubble colla.se is enha.ced by v.sible a.d infra.ed la.ers. Neither hot nor cold fusion is predicted in bubble colla.se,but the ultra.0}olet energy a. a.out 10ev.dev.loped in the bubble is sufficient to prov.de the ba.is for a.new field of chemistry ca.led ultra.ound induced a.d la.er enha.ced cold fusion chemistry.
