    "abstract": "Following precise experimental studies at the Duke Free-Electron Laser\nLaboratory, we discuss photodisintegration of deuterons with 100% linearly\npolarized photons using a model independent theoretical approach taking\ntogether $M1$ and $E1$ amplitudes simultaneously. The isoscalar $M1_s$\ncontribution is also taken exactly into account. From the existing experimental\nmeasurement on doubly polarized thermal neutron capture, it is seen that the\nisoscalar $M1_s$ contribution could be of the same order of magnitude as the\nexperimentally measured cross sections at energies relevant to Big Bang\nNucleosynthesis (BBN). Therefore appropriate measurements on deuteron\nphotodisintegration are suggested to empirically determine the $M1_s$\ncontribution at astrophysical energies.",
