This would change the Li7 into Be7 and e.g. the Ni58 into Co58. The reaction as a whole is endothermic, and both Be7 & Co58 are radioactive. Or alternatively the Li7 would become He7 and the Ni58 would become Cu58. Again unstable nuclei, and I'm pretty sure it would be endothermic, without even doing the calculation.
