Energy-differential cross sections of fragment (heavier than a-particle) production of carbon and aluminum were obtained with a specially designed Bragg curve spectrometer (BCS) and energy-time-of-flight method (E-TOF) for 70 MeV protons at 30-degree laboratory angle. The consistency of these two methods was confirmed by comparing Z=2 results each other. The energy differential cross sections of fragments for Z=3 and m=6, 7 are obtained by BCS and E-TOF, respectively. These results are compared with other experimental data, LA-150 evaluated nuclear data and QMD calculation results. The disagreements between present data and both results of evaluation and calculation show systematic trends
