Inelastic neutron scattering permits to study molecular dynamics of biomolecules such as protein and phospholipid in relation to their biological functions. The thermal neutron backscattering spectrometer IN13 in Institut Laue-Langevin (ILL), Grenoble, France, has widely been for research in biology because of its high energy resolution and wide Q range. I had an opportunity to stay in Grenoble, France, as a visiting scientist of Université Grenoble-Alpes and ILL, and to carry out neutron scattering measurements using IN13. My experience during the stay is briefly described.
