Abstract
Temperature dependent spin-lattice relaxation time, T1, measurements w ere carried out on surgically removed pituitary adenoma tissues at low temperature. Differences were found between samples; the temperature dependence of T1 showed a broad minimum below freezing. The measured d ata were fitted by theoretical lines to determine various parameters s uch as activation energy, correlation time and intensity.
