今年4月，在佐治亚州亚特兰大举行了关于壳层内电离现象的国际会议。大量的参与者和广泛的论文和讨论表明，人们对探索、理解和应用内壳层电离的兴趣越来越大。这次会议的议事录很快就会出现。是什么引起了人们对这类现象的兴趣？60年前，查德维克首次观测到阿尔法粒子轰击下的特征目标X射线，人们可能会认为，在这中间的几年里，这个领域应该已经发展到了成熟阶段。然而，直到最近，随着大范围准确的电离截面测量的积累，才有可能对重带电粒子的内壳层电离理论进行详细的测试。
An International Conference on Inner-Shell Ionization Phenomena was held in Atlanta, Georgia, during April of this year. The large number of participants and the sweeping scope of the papers and discussions signify the wide and growing interest in the exploration, understanding and application of inner-shell ionizations. The Proceedings of this conference will appear shortly. lWhat is it that holds the interest in this class of phenomena? Characteristic target x rays under alpha particle bombardment were first observed by Chadwick2 just 60 years ago, and one might have expected that the field should have progressed to a mature stage in the intervening years. However, detailed tests of the theory of inner-shell ionization by heavy charged particles have become possible only very recently with the accumulation of wide-ranging accurate ionization cross section measurements.
