We have studied the synthesis of26Al during combined hydrogen and helium-burning processes in high temperature and density conditions. The possible sites for these processes are believed to be the neutron star surfaces where the density ranges from ρ=104−107 g cm−3 and temperature range from 108−8×108 K. The screening effect which leads to an enhancement of nuclear reaction rates is taken into account whenever necessary. A detailed calculation of the abundances of26Al and27Al isotopes is presented here. Finite amounts of26Al is found to be produced atT=2×108 K and ρ=108 g cm−3 due to these combined reactions. This situation is likely to be realized during the γ-ray burst events on neutron star surface. The amount of material processed in the burst sources is very little compared to the amount of material processed in Novae or Supernovae. Thus it is suggested that rather than contributing to the overall amount of26Al, γ-ray bursts are likely to contribute more significantly to the inhomogeneity of26Al distribution in interstellar medium.
