We derive simple expressions for the low-energy behavior of direct radiative capture cross sections, particularly those important in solar nucleosynthesis, such as He3()Be7, H3()Li7, and Be7(p,)B8. Our results for the He3()Be7 reaction are inconsistent with a measurement by Rolfs et al. NUCLEAR REACTIONS He3()Be7, H3()Li7, E<300 keV, Be7(p,)B8, E<100 keV, extrapolated S.
