摘要：

In this paper we show how ''garden variety'' cosmogenic Be-10 can be used to determine the actual form of bedrock-to-soil conversion rates on a hill slope. We apply the method to two hill slopes in California and show that measured Be-10 concentration profiles are consistent with bedrock-to-soil conversion rates that decrease steadily down slope, from a maximum at the ridge crest to zero at the slope base. This result is independent of both the maximum bedrock-to-soil conversion rate on the hill slope and the Be-10 delivery rate, if both are constant with time.
