    Proposal for the Simultaneous Measurement of the Neutron–Neutron and Neutron–Proton Quasi-Free Scattering Cross Section via the Neutron–Deuteron Breakup Reaction at E n = 19 MeV

    In order to confirm or refute the present discrepancy between data and calculation for the neutron–neutron quasi-free scattering cross section in the neutron–deuteron breakup reaction, we describe a new experi...

    Cotton Host-Microbe Interactions

    Throughout its life the cotton plant is constantly confronted by microorganisms that may be either beneficial, commensal, or pathogenic. Some of these microbes are endophytes that live in all parts of the plan...

    Photodisintegration of the Deuteron between Eγ = 2.4 and 4.0 MeV

    Big-bang nucleosynthesis (BBN) is an observational cornerstone of the hot big-bang cosmology. According to [1] the p(n,γ)d reaction is of special interest because the big-bang abundance of deuterium is most sensi...

    Hadronic Probes of Few-Nucleon Systems

    The common theme of this talk is “probing the nuclear dynamics at low energies”. This subtitle implies the study of nuclear systems at rather large internucleon distances. We will focus our attention on the th...
