Research news on lanthanum

Lanthanum is a metallic chemical element (atomic number 57) that serves as the prototypical member of the lanthanide series, characterized by the gradual filling of 4f orbitals. In its common +3 oxidation state, lanthanum forms predominantly ionic compounds with high coordination numbers and exhibits relatively low magnetic moment due to the absence of 4f electrons in La³⁺. It has notable roles in materials science and solid-state chemistry, including as a component in perovskite-type oxides, phosphors, and catalysts, where its ionic radius, polarizability, and redox behavior influence structural stability, defect chemistry, and electronic properties.

A new feature discovered in radioactive lanthanum isotopes

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The ...

Physicists observe excited states in lanthanum-120

For the first time, physicists have observed excited states in the very neutron-deficient odd-odd nucleus, lanthanum-120. The study, published in Physics Letters B, was conducted by researchers from the Institute of Modern ...
