Any of three processes of radioactive disintegration in which a Beta particle is spontaneously emitted by an unstable atomic nucleus in order to dissipate excess energy.
某些不稳定原子核为耗散其过剩能量而自发发射一个β粒子的三种放射性衰变过程的统称。
2.
Type of radioactive disintegration (see radioactivity) in which some unstable atomic nuclei dissipate excess energy by spontaneously ejecting an alpha particle.
放射性蜕变的一类,某些不稳定原子核自发射出一个α粒子以耗散过剩能量。
3.
Half-lives are characteristic properties of the various unstable atomic nuclei and the particular way in which they decay. Alpha decay and Beta decay are generally slower processes than gamma decay.
半衰期是各种不稳定原子核的特性,是它们衰变的特殊方式。α衰变和β衰变一般比γ衰变为慢。
