Abstract

To investigate the electronic state of La<SUB>3</SUB>Ir<SUB>2</SUB>Ge<SUB>2</SUB>, we have carried out <SUP>139</SUP>La-NQR measurement. In the normal state, the spin–lattice relaxation rate 1⁄<I>T</I><SUB>1</SUB> is proportional to the temperature <I>T</I>. 1⁄<I>T</I><SUB>1</SUB> shows a small coherence peak just below the superconducting transition temperature <I>T</I><SUB>c</SUB>=4.7 K and decreases exponentially well below <I>T</I><SUB>c</SUB>. La<SUB>3</SUB>Ir<SUB>2</SUB>Ge<SUB>2</SUB> is found to be a BCS superconductor with an energy gap 2Δ(0)=3.52<I>k</I><SUB>B</SUB><I>T</I><SUB>c</SUB>.
