摘要：

The utilization of the pulse-shape-discrimination technique is demonstrated to improve the precision and accuracy of radiocarbon measurements by conventional-size carbon dioxide gas-proportional counters. Up to now, the maximum measurable age of a sample has been increased from 51,000 to 57,000 y B. P.
