Proton dripline in a new formula for nuclear binding energy
Chirashree Lahiri, G. Gangopadhyay
TL;DR
This paper introduces a new phenomenological mass formula to predict the proton dripline, showing it allows for easier synthesis of heavier elements in X-ray bursts compared to previous models.
Contribution
A novel mass formula is proposed that improves predictions of the proton dripline and nucleosynthesis pathways beyond nickel.
Findings
New formula predicts proton dripline up to A=80
Easier synthesis of heavier elements in X-ray bursts
Comparison shows differences with existing mass formulas
Abstract
The location of the proton dripline in a new phenomenological mass formula is calculated. Predictions of different mass formulas for the dripline are compared. The implications of the new mass formula for rapid proton nucleosynthesis beyond Ni are discussed. It is seen that the new formula indicates that masses up to A=80 are easily synthesized in a typical X-ray burst.
