Abstract
Two-dimensional Fermi liquid theory applied to the normal state of hig h T-c cuprate materials predicts that the product of electrical resist ivity and nuclear spin-lattice relaxation time should be proportional to temperature. This is vindicated for underdoped YBa2Cu4O8 above a ce rtain crossover temperature. This latter temperature is then used to e stimate the binding energy of the composite charged (2e) Bosons alread y present above the critical temperature T-c.
