β衰变 1. The influence of strong magnetic field on beta decay in the crusts of neutron stars; 中子星壳层中强磁场与β衰变 2. The results show that a weak magnetic field makes little effect on the beta decay,but a strong magnetic field(B>1012G) improves the rate of beta decay obviously...
是否存在正负beta..一个类似的是无中微子双贝塔衰变,如果中微子是马约拉纳费米子,那理论上就会有这种过程,不过目前实验还没观测到。对产生的话我不知道能否通过类似的过程实现,对这方面不是很了解。如果要找类似双贝塔衰变的过程则
