摘要：
In a previous work we showed that the introduction of a cosmological constant of the form Lambda = 3 alpha((R) double over dot/R) + 3 eta((R)over dot/R)(2) + 3Y/R-2 provides more room for consistency with the recent observational data on Hubble's constant and the age of the universe. In this letter, we study the effect of the model on primordial He-4 abundance and find that the model leads only to a slight increase in 4He.
