Abstract

exposure buildup factors(eBF) for some spin ice compounds such as Dysprosium Titanate (Dy 2 Ti 2 O 7 ), Dysprosium Stannate (Dy 2 Sn 2 O 7 ), holmium Titanate (ho 2 Ti 2 O 7 ) and holmium Stannate (ho 2 Ti 2 O 7 ) useful in nuclear engineering have been computed for photon energy range 0.015 to 15 MeV upto penetration depth of 40 mean free path. The eBF for these compounds were found to be the largest at photon energy 15 MeV excepts in low energy. The eBF for the compounds containing tin were found to be the largest as well as shown a peak at 30 keV photon energy.

Highlights

  • With the availability of radioactive-ion nuclear beams the fusion of colliding nuclei with the excess of neutron/proton ratio or near the drip line has attracted central position in the current days research [1,2,3,4,5,6,7,8,9,10,11,12,13,14]

  • We extend the work to include new series like Ne-Ne

  • We consider the collisions of three different series namely; A1Ca + A2Ca, and A1Zr + A2Zr to cover wider mass range

Summary

INTRODUCTION

With the availability of radioactive-ion nuclear beams the fusion of colliding nuclei with the excess of neutron/proton ratio or near the drip line has attracted central position in the current days research [1,2,3,4,5,6,7,8,9,10,11,12,13,14]. The enhancement of the fusion cross section has been observed for neutron-rich projectile [18,19,20,21]. The properties of various neutron-rich nuclei with different N/Z -ratio are studied in the literature e.g.: 9-102He(N/Z =3.50-4.00; where N and Z are the neutron and proton content of the nucleus), 6,.
