Threshold-Aligned Pygmy Dipole Strength in Astrophysical $(n,{\hat{I}}^3)$ and $({\hat{I}}^3,n)$ Reactions

T. Ghosh, A. Kaur, N. Paar

Reaction-rate calculations relevant to r-process nucleosynthesis depend sensitively on the nuclear ${\hat{I}}^3$-strength function (${\hat{I}}^3$SF). Here we investigate the impact of low-lying pygm…
