Abstract
A new determination of the nuclear spin relaxation rates of the 69Ga and 71Ga isotopes in liquid Ga is reported. The observed rates are shown to consist of two contributions, one due to the magnetic interaction of the dipole moment and the other arising from the electric quadrupole interactions. The respective rates for these two processes are given by R1M(69)=(1.52T+523)s-1 and R1Q(69)=(0.48T+202)s-1 in the range 3001 and T2 was observed and the relaxation rates especially R1Q, are consistently smaller at all temperatures. The origin of R1Q is most probably quadrupolar coupling to vibrational modes in the liquid.Keywords
