摘要：

We examine the production and decay mechanisms of doubly strange S = -2 hypernuclei, focusing on reactions induced by kaons. The production of XI and XI* (1530) hyperons in (K-, K+) reactions on nuclear targets is considered, including the possibility of observably narrow XI single-particLe bound states. We present estimates of the baryon (n, p, LAMBDA) decay widths of XI states, based on calculated XIN --> LAMBDALAMBDA mixing amplitudes, which indicate that such excitations could be considerably narrower in light nuclei than the estimated XI decay width of 5-10 MeV in nuclear matter.
