Results of high resolution neutron time of flight spectroscopy measurements on natural lanthanum (99.9% ' La) are presented. Plots of o, vs E are given to 76 keV. Values of Ep and gl "arepresented for all 150 ' La levels observed to 26 keV. About 50 of these levels are probably p levels, based on Bayes' theorem and the minimum gl " for detection vs E. Intermediate structure seems to be present in Sp = -Qgl e/n8'. From 6 to 18 keV, 10~Se= 0.50. Two strong levels at 3 and 3.5 keV, and several strong levels in the 18.5 to 26 keV region, boost Sp to a value 10 Sp= 0.76 for the full 26 keV range. A standard analysis that ignores intermediate structure and uses a single channel Porter-Thomas fit to the entire gI""population yields 10 Sp = 0.76 + 0.13, Dp = 208 + 10 eV, and 10 S 1 = (0.6+p, 2 ).
