标题： The photodisintegration of cosmic ray nuclei by solar photons: the Gerasimova-Zatsepin effect revisted

摘要： 高能宇宙射线粒子的质量测量这一有趣的可能性是由格拉西莫娃和扎特塞平（1960年）提出，他们建议通过观测几乎同时到达地球的成对广延大气簇射来实现。这类簇射将由大量核子与太阳辐射场相互作用后发生光致裂变所产生的核碎片形成。本文中，我们在现有和提议的高能及超高能宇宙射线探测器的背景下重新审视了这种可能性，并考虑了一个简单但现实的行星际磁场模型。然而，直接观测宇宙射线的质量裂变仍然具有挑战性。 显示英文摘要

摘要： The interesting possibility of measuring the masses of high energy cosmic ray particles by observing pairs of extensive air showers arriving at the earth nearly simultaneously was proposed some years ago by Gerasimova and Zatsepin (1960). Such showers would be created by the nuclear fragments originating as a result of the photodisintegration of massive nuclei interacting with the solar radiation field. In this paper we re-visit this possibility in the context of existing and proposed detectors of high and ultra-high energy cosmic rays considering a simple, yet realistic, model of the interplanetary magnetic field. The possibilty of observing the mass fragmentation of cosmic rays directly, however, remains challenging.
