Rare earths (4) and actinides (5) provide variety of interesting states realized with competing interactions between the increasing number of electrons. Since crystal field splitting of many-body electron system is smaller than the bandwidth, (1) high resolution experiments are needed, (2) essentially no clear spectrum with well defined peaks is expected in itinerant Ce and U compounds, and (3) Np and Pu is strictly regulated. Therefore, systematic research on magnetic excitations by neutron scattering experiments of localized compounds and rare earth iso-structural reference is useful. We describe the electron states of heavy electron compounds NpPdAl and actinide and rare earth based iso-structural family.

The enhancement magnetic resonance mode of FeTeSe is limited around Q = (
, 0). Q dependence is found to be consistent with a theoretical simulation of the magnetic resonance mode with the sign-reversing order parameter of s
wave.

A series of meetings to discuss future neutron/muon sources and instruments at Materials and Life Science Experimental Facility (MLF) in Japan Proton Accelerator Research Complex (J-PARC) has been held since 2017. Each of the neutron instrument groups in MLF proposed required features for future instruments, while addressing issues of the current instruments and facilities. This report compiles the presentation materials presented by the neutron instrument groups in the meetings to help future discussion for the coming MLF.

The joint user meeting for the neutron spectrometers in the Materials and Life Science Experimental Facility (MLF) at J-PARC, "DIRECTION 2018", was held jointly by J-PARC MLF, KEK-IMSS, and CROSS. This meeting was purposed to encourage users' activities and collaborations between users and instruments on six beamlines BL01 (4SEASONS), BL02 (DNA), BL06 (VIN ROSE), BL12 (HRC), BL14 (AMATERAS), and BL23 (POLANO). In this meeting, 14 talks and 21 posters were presented, which reported recent research activities using the instruments, and the current status of the instruments and sample environments. This report compiles the presentation materials and their abstracts.
