A pronounced spike at low energy in the strength function for magnetic
radiation (LEMAR) is found by means of Shell Model calculations, which explains
the experimentally observed enhancement of the dipole strength. LEMAR
originates from statistical low-energy M1-transitions between many excited
complex states. Re-coupling of the proton and neutron high-j orbitals generates
the strong magnetic radiation. LEMAR is closely related to Magnetic Rotation.
LEMAR is predicted for nuclides participating in the r-process of element
synthesis and is expected to change the reaction rates. An exponential decrease
of the strength function and a power law for the size distribution of the
B(M1) values are found, which strongly deviate from the ones of the GOE of
random matrices, which is commonly used to represent complex compound states.Comment: Proceedings of the conference on Nuclei and Mesoscopic Physics 2014,
