Heavy Elements Produced in Supernova Explosion and thier Propulsion in the ISM

We study the r-process path at temperatures from 1.0-3.0 × 10⁹K and neutron number density from 10²⁰-10³⁰ cm ^-3. At low density of 10²⁰ cm^-3 and T ₉ = 2.0, the path contains all the elements as given by experimental data of Wapstra et al. (2003). The element ₉₈ Cf ²⁵⁴ shown by supernova light curves is found in our results. We take iron (Z = 26) as seed for calculation of abundances for supernova.
