Abstract
Stellar rates for the reactions ^(27)Al(p,-y)^(28)Si and ^(24)Mg(ɑ,-y)^(28)Si have been calculated from new cross- section data for these reactions. The contributions to the interaction rates, (σv)_(py) and (σv)_(ay), and to the corresponding photodisintegration rates, λ_(yp) and λ_(ya), from the excited states of ^(27)Al, ^(24)Mg, and ^(28)Si are discussed. The calculated interaction rates, N_A(σv), are listed for temperatures from 0.1 X 10^9º to 5.0 X 10^9° K; two- and four-parameter fits are given for N_A(σv) as a function of temperature.
