The possibility of a detailed investigation of weak {lambda}N interaction in the {sub {lambda}}{sup 10}Be and {sub {lambda}}{sub /10}B hypernuclei, which stand out owing to their {alpha}{alpha}N{lambda} cluster structure, is discussed. The detection of a few groups of correlated {alpha}{alpha} pairs will furnish information about decays to specific states of product nuclei ({sup 8}Be*, {sup 8}Li, {sup 8}B), thereby paving the way to a phenomenological analysis of the weak decays of p-shell hypernuclei. The ratios of the intensities of individual alpha-particle groups to be measured in experiments at the cyclotron of the Joint Institute for Nuclear Research (JINR, Dubna) will provide a useful criterion for choosing an appropriate model of weak {lambda}N interaction. The current state of hypernuclear physics is briefly reviewed.
